The Canadian province of Prince Edward Island first required its residents to register their motor vehicles and display licence plates in 1913; only rear licence plates have been required since 1976.

Passenger baseplates

1919 to 1961

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 standardised the size for licence plates for motor vehicles (except those for motorcycles) at 6 in in height by 12 in in width, with standardized mounting holes. The first Prince Edward Island licence plate that complied with these standards was issued six years beforehand, in 1950.
