Ford of Canada engines were all Canadian. They did a lot of things differently than across the river in Dearborn. Ford USA did things in similar fashion so the dates are for the engines and not the bodies. The actual car completion date is not part of the equation. There were too many assembly plants all over the country and the world so all the components had to travel many miles from Detroit for a lot of the cars built. A person can see that from the day the engine was stamped to the completion of the car could vary from several days to several weeks depending on where it was assembled. Characteristics of a particular car will tell a lot but that's only if the car is an unmolested original. It's getting harder to find cars that fit that description.

Canadian cars were assembled in the same place for the most part so the time frame is likely shorter but it depends on how well the cars were moving/selling during the depression. Some Canadian product was sent to Australia and other Commonwealth countries. The engine pieces were cast at a different location than the car assembly work so there was some lag time due to that as well. Sarnia was where the engine foundry plant was.
