Before WWI Canada traded with Britain, but after we started trading with the US Canada starts trading pulp, paper mills and mining with US But instead of lending money to Canadian business Americans set up branch plants Branch plants are factories run by a foreign country on our soil Car makers could avoid Canadian tariff's this way because the factories were in Canada. GM, Ford and Chrysler overtake Canadian car industry America's investment in this led to a shortage of secondary industry in Canada Because all these plants came into Canada it caused Canada to not have any power
Summary
In summary, the Branch Plants in Canada were not the best thing for the economy and caused the US to have power over us. The factories were a step in the right directions but the fact that we were not running them ourselves is what pulled us down.
