I partly agree but Canada's housing crisis is quite exceptional in my opinion. I had the chance to travel a bit and I rarely saw a ratio annual salary to house prices that bad, even in cities that have always topped the high cost of living rankings. I mean Toronto and Vancouver have been out of reach for the "normal" working class for quite some time, but we are now adding Ottawa and Montreal to the list. Frankly in Ottawa is becomes difficult to find anything decent for less than 600K (advertised), plus bidding war fees, plus taxes and other fees etc... easily 700K in the end + most probably strata fees to pay every month. It's just absurd compared to the average salary in Ottawa. Sure there are other cities but as you said it depends if you can find a job there.
Do you own a home in Japan before you move to Ontario? Is there a housing crisis in Tokyo? How' the annual salary there compare to Ontario?
