EDIT (for your edit): >To clarify, I mean modestly wealthy individuals attempting to take advantage of hopeful entrepreneurs is SOP in Canada. I've seen it on the west coast first hand, and have reports from the east coast about similar things.
Again, this is NOT the standard operating procedure in Canada. I'm sure there are individuals who have no qualms about squeezing entrepreneurs, but I can't imagine this is any different from US. The one problem I found is that, though Canada (Ontario at least) has a wonderful Angel network, and phenomenal government programs (e.g. FedDev, SRED), there is a lack of Series A (and later) VC money.
