US Federal specs because they often were not confirmed until June of the

In 1972, all provinces in Canada agreed to make all road signs metric by
1977. The changeover was completed in September 1977.

Manufacturers started providing metric speedometers (with imperial units
also marked)/odometers, generally around 1975, although the timing varied
by manufacturer. By 1978, all new cars sold in Canada (except old stick) should
have been equipped with metric speedometers/odometers.
