"Junior level positions, which in Toronto translates to around $50k - $60k. I could make the same amount of money waiting tables if I really wanted to."

So the going rates in Canada are in that range. I interviewed for a remote senior position (5+ years exp) for a start-up in Toronto (that from brief research looked to be profitable, so I went ahead).

My jaw dropped when they said they were targeting $25 (CAD) an hour, with the exchange rate that's less than $19 (US) an hour. My sentiment was the same as yours, at $19 (US) an hour I could make the same amount of money teaching plain English anywhere in the world. It looks like they don't even do a cross-check for other industry rates, just fluent English can net you the same rates as an English teacher in practically any market.
