Huh, that is a really interesting question.
It's not as trivial to calculate as it is for Bitcoin, where you can multiply the moneys held by the change in exchange rate -- essentially no prices as denominated in BTC, while most prices most Canadians deal with are denominated in CAD. For most Canadians, the ratio of their income and rent or groceries will stay the same, so in some senses they haven't lost anything. But the price they pay for imports, like computers and oranges, will go up, so they have definitely lost something. I wonder what the balance comes out to.
