Parking Meters Arrive in Ottawa

25 April 1958

By the time of the Great Depression the automobile had replaced the horse-drawn carriage. In 1929, five million cars were produced in the United States, with another quarter million made in Canada. City streets were becoming clogged with vehicles, and parking was becoming a serious problem everywhere. Through the working week, people drove their vehicles to downtown offices, and parked them on neighbouring streets for eight hours or longer. This left little room for shoppers. Although the Depression drastically slowed the production and sale of cars, it didn’t solve the parking problem. Carl C. Magee, a noted American publisher, came up with a solution–the coin-operated parking meter. (Magee had become prominent during the 1920s for publicizing the Teapot Dome Scandal, the biggest U.S. political scandal prior to Watergate, that led to the Secretary of the Interior being jailed for corruption.) Magee, in co-operation with University of Oklahoma engineers Holger Thuesen and Gerald Hale, developed a working prototype. In May 1935, Magee filed a patent in the United States for a coin-controlled device, receiving U.S. patent 2,118,318 three years later for his invention. American cities took to the new invention like proverbial ducks to water as a way of encouraging motorists to vacate parking spaces. The fact that parking meters were a real money spinner certainly helped too. Meters paid for themselves in four or five months.

Oklahoma City installed Magee’s “park-o-meter” on its streets in July 1935, just weeks after Magee filed his patent application. Reporting on the event, The Ottawa Journal called the new device the “automat of the curbstone,” describing it as “a metal hitching post with meter attached” that promised “to solve the pest of the streets – ‘the parking hog.’” It opined that people will be watching the experiment with great interest.

Ottawa wasted little time in exploring the possibility of introducing parking meters to the streets of the nation’s capital. In 1936, City Council received an offer from one O. G. O’Regan to install parking meters in downtown Ottawa. In a letter, O’Regan explained that the cost of the meters would be paid by parking fees, and that after the costs were met, the revenue would accrue to the city. Ottawa’s Board of Control said that O’Regan should speak to the Automobile Club, the Board of Trade and other groups to educate the public about such a drastic change in parking regulations. In an editorial the Journal said that the parking meter was “so new that probably many people are unfamiliar with it.” Assessing the pros and cons of a trial, the newspaper argued that if free street parking is not a “right,” then Ottawa might as well make some revenue from it “if the privilege is to be extended.” Also, if meters reduced casual parking, merchants might benefit. However, the newspaper was uncertain whether Ottawa citizens would take kindly to the idea, and wasn’t sure if meters could be used with parallel parking.

Ottawa did not take kindly to the idea. It took three attempts and twenty years before City Hall got the votes to install meters. On the first attempt in 1938, the Traffic Committee and the Board of Control recommended the installation of 903 meters in downtown Ottawa for a six-month trial period. Supporters of the measure hoped that meters would be more effective than existing parking regulations in curbing lengthy parking stays. In 1937, 14,000 parking tickets were handed out to motorists who had overstayed the 30-minute parking limit, but only 900 fines were issued. Opponents argued that instead of unsightly meters, parking problems could be addressed through the enforcement of existing rules. Mayor Stanley Lewis opposed meters as did merchants who feared losing business if free parking was eliminated. A concession on the part of meter supporters to reduce the charge for the first twelve minutes to only one cent was not sufficient to change minds. With Toronto and Montreal having turned down metered parking, Council rejected meters on an 18-8 vote. The measure was put onto the backburner for a decade.

In 1947, the issue resurfaced. By this time, meters had apparently been installed in 1,200 U.S. cities and 49 Canadian communities, including Kingston, Oshawa and Windsor. Once again, the Traffic Committee and the Board of Control favoured their introduction. But Stanley Lewis, who still occupied the mayor’s chair, remained a steadfast opponent. At Council, the debate was fierce. Supporters argued that metered parking would allow for a more equitable distribution of limited parking spaces, would speed up business, reduce congestion, and increase municipal revenues. The anti-meter faction argued that meters would ruin the look of Ottawa, would clutter sidewalks, and that shoppers would avoid areas that had metered parking. Some also contended that metered street parking was a “nuisance” tax on motorists, and that their advantages were unproven. One alderman suggested that to reduce congestion, he would ban all parking on Bank and Sparks Streets, and convert part of Major Hill’s Park into a parking lot. “The park is only frequented by tramps, and the public do not go there.”

In December 1947, Council narrowly voted (12-10) in favour of installing parking meters for a one-year trial, and issued a request for tenders. One would think that this would have been the end of the matter—far from it. Two firms, the Mi-Co Meter Company of Montreal and the Mark Time Meter Company of Ottawa, submitted bids for the contract. Early the following year, the Board of Control selected Mi-Co on the basis that it offered the lowest price. However, City Council subsequently rejected the Mi-Co bid in favour of Mark Time meters. While Council did not have to select the lowest bid, the rationale for overturning the Mi-Co bid was murky. The Mi-Co Meter Company, whose meters were actually made in Ottawa by a company called Instruments, Ltd, indicated that it would seek an injunction to stop the city from signing a contract with Mark Time on the grounds that it had won the tender since its meters were cheaper and conformed to City specifications whereas Mark Time meters did not. Among other things, the City had specified that the dial indicating the amount of time available was to be visible on both sides of the meter. This requirement that was not met by Mark Time meters. After another stormy Council session, Council voted 17-7 to rescind the awarding of the contract to Mark Time. It was a pyrrhic victory for Mi-Co. Ten days later City Council overturned the parking meter trial on an 18-2 vote. According to the Ottawa Journal, this decision “positively, definitively, officially and finally” meant that parking meters would not be installed on Ottawa streets.

With the parking debate in abeyance in Ottawa, Eastview (Vanier), which was a separate municipality, got a jump on its municipal big sister by introducing parking meters in May 1951 along Montreal Road. The charge was one cent for the first twelve minutes and five cents for an hour of parking time from 8am to 8pm Monday to Saturday. The experiment was a great success with congestion along Montreal Road substantially reduced. The fine for a parking violation was $1 if paid within 48 hours at the police station, or $3 if the infraction went to court.

Shortly afterwards, despite the “definitive” decision not to install parking meters in neighbouring Ottawa, the City Council’s Traffic Committee again recommended the installation of meters on certain Lowertown streets and well as on Lyon, Sparks and Queen Streets. But with Charlotte Whitton assuming the mayor’s chair in 1951, the recommendation went nowhere. The pugnacious and irascible Whitton was dead set against parking meters. “[If] we want space on our streets for moving traffic, we surely don’t want to rent out public streets and give people the right to store their cars there,” she said. She favoured more off-street parking instead.

It wasn’t until after Whitton had been dethroned in 1956 that the parking meter issue resurfaced in any significant manner at Ottawa City Council. By this time, meters had become a familiar part of the urban landscape in most North American towns and cities. Toronto had succumbed in 1952 and Montreal two years later. The Journal newspaper had also for several years run a series of favourable articles on the success of meters in other towns in curbing traffic congestion and, incidentally, raising huge sums for municipal coffers. These articles were helpful in preparing the ground for parking meters. In mid-December 1957, Ottawa’s Civic Traffic Committee unanimously recommended the installation of parking meters, the last outspoken critic of the machines on the Committee having thrown in the towel. A few days later, City Council passed the measure virtually without debate, agreeing to install meters in central Ottawa in the area bounded by Laurier, Kent, Wellington and Elgin as well as in Lowertown along Rideau from Mosgrove (located where Rideau Centre is today) to King Edward and along bordering side streets for one block.

To help avoid the contract problems that the City had ten years earlier, precise specifications were issued in the call for tenders. Four companies—Sperry Gyroscope Ottawa Ltd with its Mark Time meter, the Duncan Parking Meter Company of Montreal with its Duncan “50” and Duncan “60” models, The Red Ball Parking Meter Company of Toronto, and the Park-o-Meter Company also of Toronto—submitted bids to install 925 meters. Nettleton Jewellers examined the clockwork mechanism of all test machines submitted with the tenders. The winner was the Duncan Parking Meter Company of Montreal for its economy Duncan “50” model at $55 each.

Within weeks of the tender being accepted in February 1958, meter poles began to sprout on Ottawa streets. After testing, the first meters went “live” on Rideau Street on Friday, 25 April 1958. Traffic Inspector Callahan said that the meters were effective immediately and “must be fed” wherever they had been installed. Motorists were also given instruction on how to park—with front wheels opposite the machines. If a car occupied more than one space, both meters would have to be fed, five cents for 30 minutes, 10 cents for an hour. It was also illegal for motorists to stay longer than one hour; topping up the meter was not permitted. A parking infraction led to a $2 ticket. The meters were a great success, especially financially. The meters began pulling in $3,500 per week, considerably more than had been expected, with annual maintenance and collection expenses placed at only $20,000.

Over the next half century, the ubiquitous parking meter ruled downtown curbsides, standing every car length or two depending on whether single-headed or double-headed machines were being used. But in the 2000s, single-space curbside meters began to give way in Ottawa to multi-space machines (Pay and Display) that gave motorists a slip of paper that indicated the expiry time to be placed on the dashboard. This innovation permitted more cars to be parked on a given street, and eliminated “free” parking when a motorist parked in a spot with unused time on a standard meter. It also helped to reduce the clutter of unsightly meters on city sidewalks.

Other technological advances are also reducing the number of parking meters. Some communities have adopted in-vehicle parking meters—an electronic device that motorists can charged up and display on a car window. Others have embraced pay-by-phone parking with licence plate enforcement. In 2012, pay by telephone parking arrived in Ottawa through a system called “PaybyPhone” that is available in major cities around the world. After registering, a motorist enters a location number and selects the desired length of parking time up the permitted maximum. The parking charge is automatically debited to a credit card. Parking enforcement officers have a hand-held device that has real-time access to licence plate numbers and paid vehicles.

Looking forward, one can envisage further technological changes that could accelerate the demise of the parking meter, including in-car sensors and shared, autonomous vehicles that people call when needed. The parking meter, even the modern, multi-space machines now found on Ottawa streets, may soon become as rare as a telephone call box.

And One More April Entry from James Powell's Blog:

The End of the Crippler

18 April 1955

Thanks to vaccines we no longer live in fear of many infectious diseases that used to stalk the world killing millions each year, and maiming or crippling tens of millions more. By the early 1950s, Canadian children were routinely immunized against smallpox, diphtheria, whooping cough and tetanus. But several diseases remained to be conquered. One of the most feared was poliomyelitis, also known as infantile paralysis for its propensity to affect the young, or “the Crippler.”

The disease is caused by the poliovirus, a type of enterovirus of the family Picornaviridae. It was first isolated in 1908 by the Austrian researchers and physicians Karl Landsteiner and Erwin Popper. The virus has three serotype versions (PV1-Brunhide, PV2-Lansing and PV3-Leon). All are virulent, though PV1-Brunhide is the most common strain, and the one most associated with paralysis. Most people who come into contact with the polio virus experience no symptoms beyond a sore throat, a gastrointestinal upset, a slight fever, and a general malaise. Called “abortive polio,” this is considered a minor illness that leaves no permanent effects. A small percentage of victims experience “aseptic” polio that also involves severe neck, back and muscle pain, as well as a bad fever. In a still smaller percentage of sufferers, the polio virus attacks the central nervous system leading to muscle flaccidity, especially of the limbs, and paralysis. Depending on what part of the nervous system is affected, “paralytic” polio is classified as spinal, bulbar, and bulbospinal. In some cases, the diaphragm and chest muscles are affected. Sufferers of this form of the disease need help to breath. In 1927, two Harvard researchers invented the “iron lung,” into which paralysed patients were placed to aid their breathing mechanically. Although most were able to leave the machine after several weeks, some were confined for years, or had to use a portable breathing apparatus. Polio suffers whose limbs had become paralyzed sometimes recovered their use after a few weeks. However, some many were left permanently disabled. Two to ten per cent of people stricken with paralytic polio died. There is no cure for the disease, only prevention.

Although polio has been around for thousands of years, it didn’t use to have the fearful reputation that it had during the first half of the twentieth century. For the most part, people had acquired a natural immunity to the disease.  But as living standards and hygiene improved, the incidence of the disease paradoxically increased. The natural immunity that protected people had been weakened or lost. According to Christopher Rutty, a medical historian, fears about polio, heightened by publicity, were disproportionate to the risk of catching the paralytic form of the disease. But frightened parents told their children to “regard [polio] as a fierce monster” that was “more sinister than death itself.” The fact that people at the time didn’t understand the transmission mechanism of the disease (typically faecal-oral) made it all the scarier. You didn’t know what to do to protect yourself and your family. When outbreaks occurred, often during the summer months, health officials in epidemic areas closed cinemas, playgrounds, and delayed school openings. In Ottawa, when the federal government announced in 1950 that the water from the Rideau River would be temporarily diverted to allow for repairs near its outfall into the Ottawa River, residents of Sandy Hill, fearful of polio-infected flies that might breed in exposed marshes and refuse, lobbied for the repairs to be delayed until after the summer polio season.

People stricken with polio were sent to special isolation hospitals for a minimum of seven days required by provincial law. Their families were quarantined. Ottawa’s Strathcona Isolation Hospital was one of six designated centres for the treatment of polio in Ontario. The other centres were located in Toronto, Kingston, London, Hamilton and Windsor. The Strathcona Hospital’s “territory” ran from Pembroke to Morrisburg. In 1953, the old hospital was closed when a new East Lawn Pavilion with isolation facilities was opened at the Ottawa Civic Hospital. Seventeen patients were transferred from the Strathcona facility, including one in an iron lung. Although this was a time before provincial health insurance (OHIP), the care for polio victims was paid for by the provincial government. Later, following complaints by doctors that they couldn’t submit bills to well-to-to polio patients, the government modified the rules to allow doctors to charge wealthy patients. Poor patients continued to receive free care at teaching hospitals connected to universities.

Following the election of Franklin Roosevelt at President of the United States in 1933, who was himself a polio survivor, the medical profession in the United States and Canada took aim at the disease. Funding for research into the development of a vaccine was provided in the United States by the National Foundation for Infantile Paralysis that had its roots in a private anti-polio organization started by the Roosevelt family. The Foundation sponsored an annual March of Dimes campaign supported by Hollywood stars to raise money to find a cure for the disease and to care for polio victims. In Canada, a parallel organization called the Canadian Foundation for Poliomyelitis was founded in Ottawa in 1949. The Canadian Foundation held the first Canadian March of Dimes campaign the following year. Newspapers across the country carried the photograph of “Linda,” a child polio victim wearing iron leg braces. In Ottawa, twenty-five hundred blue and red checkered collection boxes were distributed in stores, banks and restaurants.

In 1953, North America experienced it worst outbreak of polio in decades. In Canada, there were 8,878 reported cases, mostly in Manitoba and Ontario, with a death rate of 3.3 persons per 100,000 population, far higher than during earlier outbreaks.  Ottawa had 100 recorded cases by the end of that year’s polio season with four deaths. To help control the spread of the disease, Dr J. J. Dey, the city’s medical officer of health, advised Ottawa citizens not to drink unpasteurized milk, not to jump into water when the body was tired, and to avoid fatigue. He also told people to stay away from crowds, to keep the house free from flies, and to wash all fruits and vegetables. More usefully, he advised people to wash their hands frequently, and to boil drinking water if one had any doubts.

Fortunately, by this time, a vaccine was close at hand. In 1949, Harvard scientist Dr John Enders discovered that the polio virus could be propagated in the organs of monkeys. The following year, the Polish-born virologist Hilary Koprowski developed an experimental oral vaccine using a live but weakened virus of the PV2-Lansing variety of the disease, and successfully immunized some twenty children in New York State.

Meanwhile, at the University of Pittsburgh, Jonas Salk was working on determining the number of different strains of polioviruses and developing a vaccine using dead viruses that would be effective against all strains of the disease. Connaught Laboratories at the University of Toronto, supported by a federal grant as well as money provided by the Canadian March of Dimes, was also developing the procedure for producing industrial-size quantities of the polio virus, a necessary and vital step for the mass production of the Salk vaccine. Related work was conducted at the Institute of Microbiology and Hygiene in Montreal. Connaught later supplied much of the virus that went into making the Salk vaccine in North America as well as making the vaccine itself for the Canadian inoculation campaign.

By 1954, Salk who had safely tested his vaccine first on his family and then on 700 volunteers was ready for a large-scale test. He organized a trial involving two million children. Half received a three-shot dose of the experimental vaccine over a period of several weeks with the other half receiving placebos. Most of the children were American. But U.S. authorities offered 50,000 doses to Canada. Health departments in Alberta and Nova Scotia took up the offer and inoculated thousands of young children. In mid-April 1955, the results of the trial were announced to a packed conference room at the University of Michigan: polio had been defeated! The vaccine had been 80% effective in protecting children from the disease. The relief was palpable. Immediately, steps were taken to inoculate all children in North America starting with those in Grades 1 and 2.

In Canada, the inoculations were paid for on a 50:50 basis by the federal and provincial governments. Youngsters in Toronto and Pembroke received the first dose of the vaccine in early April even before the official announcement of Salk’s successful mass trial. The inoculation programme began in Ottawa on Monday, 18 April 1955. That morning, Grade 1 and 2 students at four public schools (Elgin, Lady Evelyn, Borden and Cambridge) and five separate schools (Ste Famille, St Patrick, St Jean Baptiste, St Anthony and Christ the King) received their first round of shots. That afternoon, five more schools were visited by teams of nurses. Children in remaining schools received their shots through the week. Parents had to sign a consent form for their children to receive the inoculation with the warning that if the children missed the first shot, they couldn’t receive the subsequent shots. Across the Ottawa River in Hull, the inoculation programme started in May with children aged two to three years since that age group had been most affected in Quebec during the 1953 epidemic.

In the midst of the roll-out of the continent-wide vaccination campaign, disaster struck.  Some children in the United States came down with polio after having received their shots. Several died. The problem was traced to poor quality control at the Cutter Laboratories of Berkeley, California, one of six American vaccine manufacturers. Their vaccine contained live instead of dead viruses. According to the Journal of Pediatrics, the vaccine had been rushed. The U.S. vaccination programme was temporarily suspended despite the coming onset of the 1955 polio season. In Canada, Health Minister Paul Martin Sr faced one of the toughest decisions of his life: should the Canadian programme also be suspended as Prime Minister St Laurent wished? With all of the Canadian vaccine produced at Toronto’s Connaught Laboratories, and having full confidence in Canadian scientists and doctors, he ordered the Canadian programme to go ahead as planned. No Canadian child came down with polio as result of the vaccine.

By August 1955, the number of polio cases in Canada and the United States had dropped dramatically even though only a portion of children had been immunized. In November, Paul Martin publicly stated “I don’t think there can be any doubt that it [the vaccine] has had some effect.” By 1962, the number of reported polio cases in Canada had fallen to only 89.

In the early 1960s, the Salk vaccine was generally replaced by an oral vaccine using live but weakened viruses developed by Albert Sabin who drew on the earlier work of Hilary Koprowski. The Sabin vaccine was cheap to produce and administer and was very powerful—95 per cent effective after three doses (one for each polio strain). Polio infection rates around the world plummeted. In 1988, the World Health Organization (WHO) launched a campaign to eradicated polio from the world supported by national governments, the U.S. Centers for Disease Control and Prevention, UNICEF, Rotary International and the Bill & Melinda Gates Foundation. In 2000, the Americas were certified as polio free. In 2014, South-East Asia was certified as polio free. By 2016, the number of reported polio cases worldwide had dropped to only 37 located in Nigeria, Afghanistan and Pakistan. The WHO estimates that because of the global vaccination campaign, 16 million people walk today who otherwise would have been paralyzed. Many, many lives have also been saved. However, war and civil strife threaten this achievement. Endemic transmission of the disease continues in the three remaining polio hotspots. With vaccination efforts disrupted in these areas, the Crippler could well return.
