Vehicle registration plates of Ontario


The Canadian province of Ontario first required its residents to register their motor vehicles in 1903. Registrants provided their own licence plates for display until 1911, when the province began to issue plates. Plates are currently issued by the Ministry of Transportation of Ontario.
The location of plates and renewal stickers is specified by the Highway Traffic Act and Regulation 628 under the Act.

The Crown

The symbol of a crown representing the Crown of Canada has appeared on almost all Ontario licence plates since 1937, when it was first used to commemorate the coronation of King George VI and Queen Elizabeth. Exceptions include the 1951 plates, and farm series plates issued in the 1980s and 1990s. Toronto politician and Orange Order leader Leslie Saunders led protests against a proposal to remove the crown in 1948, a decision the government overturned.

Passenger baseplates

1911 to 1972

In 1956, Canada, the United States, and Mexico came to an agreement with the American Association of Motor Vehicle Administrators, the Automobile Manufacturers Association and the National Safety Council that standardized the size for licence plates for vehicles at in height by in width, with standardized mounting holes. The 1954 issue was the first Ontario licence plate that complied with these standards.

1973 to present

After 1973 Ontario ceased to issue plates annually. Instead, validation was indicated by means of stickers affixed to the plates. All Ontario licence plates issued since 1973 remain valid for display, provided they have been continuously registered.
In April 2019, the Government of Ontario announced that the plates would be redesigned. The plates' design includes a surficial laminate layer manufactured by 3M. The plates have a two-tone blue background with white letters and numbers flanking a stylized white trillium, below which is the motto "A Place to Grow", taking inspiration from Ontario's unofficial anthem "A Place to Stand, a Place to Grow. Issue of the new plates began on 1 February 2020. This design was scrapped on May 6, 2020.

Green vehicle plates

Historic vehicles

Vehicles more than 30 years old and substantially unchanged since manufacture may qualify for a "Historic" registration.
Annual fees are much lower, but historic vehicles may not be used as conventional transportation. They legally may only be driven to and from events and parades where the vehicle is on display, to garages for maintenance, and other similar use cases. Annual renewal stickers are affixed to the rear plate, as with passenger vehicles.
Historic plates are not to be confused with year-of-manufacture plates.

Commercial plates 1980 to present

Unlike passenger cars, plate validation stickers for commercial vehicles are placed on the front plate, instead of the rear. This placement is consistent between trucks with visible rear plates, and tractor units where the rear plate is obscured by a trailer. Ontario vehicles registered in the International Registration Plan receive special commercial plates with "PRP" screened vertically at the left.
All pickup trucks are legally considered commercial vehicles and thus require commercial plates. However, if used strictly as a passenger vehicle, a truck may be exempt from some conditions imposed on commercial vehicles, indicated by a white or red "PERSONAL USE ONLY" sticker affixed in the top left corner of the front plate.

Farm plates

Vehicles over 3000 kg owned by farmers and used for farm-related purposes, such as working the soil, building maintenance, and the transportation of farm products, may qualify for a farm plate. Farm-plated trucks and towed trailers may also be used by a farmer for personal transportation.
To qualify, a farmer must meet a series of criteria, including membership in farming organisations and a minimum amount of income that derives from farming. Fees for farm plates are substantially lower than for passenger or commercial plates. The Highway Traffic Act also exempts farm vehicles from several requirements imposed on commercial vehicles.
Farm plates are black on white with a black crown separator, in a pattern similar to commercial plates. They have the word "FARM" written vertically on the left of the plate. Validation stickers are the same as for other vehicles, and are affixed to the front plate, as with commercial plates.

Other non-passenger plates

Trailer plates

All trailers in Ontario are considered separate vehicles and must have a permit and be plated. New owners of a trailer must register with the MTO within six days of purchase. They are then issued with a permit and a plate. Trailer plates are not renewed annually, but may be replaced if lost, damaged or stolen. Plates are affixed to the rear of the trailer. There is no front plate.
All trailers, whether used by commercial operators or others, use a same model plate. Plates are blue on white with crown separator, in a pattern and colour similar to that of passenger vehicles, with the word "TRAILER" written vertically on the left of the plate. However, they do not follow the same numbering system as other vehicles.

Dealer and service licence plates

In Ontario, motor vehicle dealers licensed under the Motor Vehicle Dealers Act use a single portable plate with the word "DEALER" on the left side and red alpha-numeric characters on a white background. It is for exclusive use by motor vehicle dealers only on motor vehicles owned as part of the dealer's inventory of vehicles for sale. It may also be used for private use vehicles that are owned as part of the dealer's inventory of vehicles for sale.
Service providers, including anyone who repairs, customizes, modifies, manufactures or transports motor vehicles or trailers use yellow and black DLR series plates.
A service plate may be used:
Private use of motor vehicles or trailers with a service plate is not permitted.

Vanity licence plates

Along with regular series plates, the province also offers vanity plates for passenger and commercial vehicles. A personalized licence plate message may contain almost any combination of letters and numbers from two to eight characters. The plates can also include one of 60 different graphics, with two to six characters. Available graphics have changed over the years, with some becoming available, while others have been withdrawn or modified. Owners selecting a graphic but no custom message are generally assigned a registration with a 12XY34 pattern, where the XY is a code indicating the design.
The province reserves the right to refuse or withdraw plates for a variety of reasons, including:
While criteria have existed since the introduction of personalized plates, accusations of excessive zeal led the McGuinty government to set up a review committee in August 2008. The eight-member committee meets weekly to review submissions. In the first half of 2013, it had rejected 3% of requests. Plates have also been withdrawn after issue.
The ownership of plates with graphic elements associated with particular groups, such as veterans or firefighters, may be restricted and require proof of eligibility.
Personalized plates with two to five characters are also available for motorcycles.

Manufacturing

Ontario licence plates were formerly manufactured by prison inmates at the Millbrook Correctional Centre in Cavan-Millbrook-North Monaghan. Upon Millbrook's closure in 2003, manufacture was moved to the Central East Correctional Centre in Lindsay, Ontario. Since 1991, all Ontario plates have been manufactured for the MTO by Trilcor Industries, owned by the province's Ministry of the Solicitor General.

Alternative Supplier

In 2016, an increase in the rate of defective plates combined with an increase in the number of registered vehicles led to the Ontario Ministry of Transport becoming unable to keep up with demand for plates. It placed an order for 100,000 units from the Waldale Irwin Holdson Group, the largest licence plate manufacturer in North America. Plates are produced by the Waldale Manufacturing facility in Amherst, Nova Scotia.
Plates from the first batch of 35,000 can be identified due to the use of embossed letters and numbers from Nova Scotia plates, which differ in appearance from Ontarian fonts.

Issues & Controversies

Defective plates from 2012

In 2012, reports began to appear of plates deteriorating earlier than otherwise expected. The reflective layers detached themselves from the metal plate, making the plate unreadable. Approximately 1% of licence plates issued have this defect. The defect has appeared in both front and rear plates. Trilcor Industries and the MTO offer a five-year warranty on plates and will replace the defective plates at no cost. Plate replacement for other reasons is done at a cost.
Conventional plates can be replaced "over-the-counter" at a licence office, but the complete process for personalized plates takes over six months.
Driving with an illegible plate is an offence punishable by fine, under the Highway Traffic Act.
In 2015, the Ministry of Community Safety and Correctional Services hired Canada's National Research Council to identify the root cause of licence plate de-lamination. The NRC's report indicated that the reflective material adhered poorly to the aluminium plates, and that embossing process stressed the materials to the point that the reflective layer would puncture and de-laminate. At that point, water and other contaminants could slip between the layers. Also, road de-icing materials contributed to the de-lamination. The report found that this problem was present in samples from all types of plates, except for motorcycle plates.
The report recommended that Trilcor work with its supplier of laminating layer to resolve the problem, and indicated that a thicker layer of material would likely perform better.

Illegality of licence plate covers

Many vehicle owners place clear plastic covers over their licence plates to protect their already defective licence plates from premature deterioration. According to Ontario's Highway Traffic Act Section 13.2, licence plate covers are considered an obstruction and are illegal in the province of Ontario. In the rare event that the officer chooses to issue the citation, the offence carries a minimum fine of $85. On the contrary, drivers operating a motor vehicle with defective number plates can be charged with the same offence. This has left defective number plate owners with little choice but to obtain replacement plates from the MTO, orders which have taken months to process.
Several motorists sought other solutions to prevent their number plates from deterioration, such as placing the front plate on the dashboard instead of affixing it to the front bumper. Others have omitted the front licence plate altogether since it is not uncommon to see out-of-province vehicles on Ontario roadways. In most cases, vehicle owners who attempted the aforementioned solutions were convicted of the same offence.

Defective plates from 2020

On 15 February 2020, two weeks after the province began issuing plates with the new design, off-duty Kingston Police Sergeant Steve Koopman posted a photo on Twitter showing a vehicle with the new plate at night, stating that "they're virtually unreadable at night". Government spokesperson Lisa Thompson, the Minister of Government and Consumer Services, stated in a news conference that the new design had undergone a "rigorous testing program", that the government had consulted with "key stakeholders" including law enforcement, and that the plates were not problematic. She also criticized the earlier "Liberal plates", referring to a batch of plates issued during a previous government that peeled. Thompson stated that manufacturing and quality control are the responsibility of 3M. The redesigned plates also caused problems for photo radar cameras, which have difficulty reading the name of the jurisdiction. The name is rendered in a smaller font size than earlier plates. The president of the Toronto Police Association stated that the organization had not been consulted on the new design.
The Ford Government had insisted for days that there was not an issue with the plates, however, on February 20, it announced that 3M would make a "enhanced licence plate" to be available in less than three weeks. On February 28, the government announced that the distribution of the defective plates would cease on March 4, that the enhanced plates would be ready by March 16 at "no cost to Ontario taxpayers", those who had already been issued the new plates will receive the enhanced version in the mail, and until the enhanced plates were ready, the government switched back to the previous plate design. This design was later scrapped on May 6.
