Does Canada produce its own line of automobiles?

Answer 1

Not anymmore. Most Canadian companies were bought out.. in some cases, the marque would be used to badge engineer American vehicles, but that was eventually phased out. However, most "US" vehicles undergo at least some of their manufacturing process in Canada.

As for vehicle manufacturers based in Canada, Western Star is the only one I can think of offhand, although the marque was actually started in the US.
