A lot depends on WHERE you live. I am sure there are people with a cabin in a remote part of BC that live on less. same would be in Newfoundland. But in Toronto, Vancouver or even other major cities?? Unless you are prepared to be a street person or something close.
Someone metioned CPP/OAS. You won't get much of that at 30 something (or even later if you don't work)
For a retired middle class couple with paid off home and full CPP/OAS living outside of major cities, a million might do it in todays $. They would have a total of about $65-$70k before tax if the money has wisely invested. But not if in GICs or the like.
