Not sure to whom I am replying- new to this whole thing. Trying to contact Bevdeforges as I have learned much from past posts. My wife and I are dual US/Canadian citizens, originally US. We have been living and working (making Canadian salary) in Ontario for 17 years. We have rrsps, tfsas and other bank accounts here. We have Iras, Roths and California state pension in US. We wonder where the the best retirement location would be from a tax standpoint. Also thinking of buying house in Ontario. Good idea? Bad Idea?
