canada is a relatively small market, compared to asia. the arguments about cost here are largely wrong - the cost has to do with shipping, not labour. these factories are mostly automated. and, if you're focusing on emerging markets, it makes sense to place your automated production facilities as close to the emerging markets as possible.

cars made in canada would be mostly made for the canadian market. given that our economy is stagnant, there's no reason to increase production. the only thing that's going to increase production in canada would be increased sales in canada, and that's not likely any time soon. even so, the increase would be relatively minor...

it really essentially has nothing to do with us, and everything to do with massive growth rates in asia and the rearrangement of production to emphasize local production, due to automation.
