I never ran into any Canadian Fords when I lived up in Kansas but there could be some that made their way down over the years. Canada did things differently than Ford USA. This site shows the numbers. They were using C18 or CB prefix followed by another letter of the alphabet and then a 4-digit sequential number. This link has the numbers. The third or forth digit was changed each time the numbers reached 10,000 depending on whether it was a 4-cylinder or a V8.

I'm not sure if the prefix was different for commercial vehicles like it was here in the USA. I'm also not sure if Canada used the special 1, 6, & 9 stamps.
