I am considering moving to Vancouver Canada. I'm trying to figure out how much I would have to make in Canadian dollars to have the same purchasing power in Canada that I do here -- considering not only the value of the Canadian dollar but also higher taxes there etc.

For example, if I make 75K per year here (in Philadelphia), how much would I have to make in Vancouver to have the same purchasing power (or purchasing power parity), to be able to have the same goods and services.

I believe that I would pay about 50% of my salary in taxes of various sorts, and then what I would have left would only have 80% of the purchasing power, per dollar in Canada, compared to per dollar in the US.) But I'm not sure and I suck at math, i.e., what it all means.

Thanks for your help!
