Thank you to KalC, who pointed out in a commentary 14 February that the draft FATCA regulations seem to include an exemption for pensions and related assets.
What is needed, I think, is expert opinion on the meaning of this section, which begins at p. 286. When I search the internet for interpretation, I only find sources like Deloitte & Touche, which are addressing their clients needs, chiefly business.
I have written to Barrie McKenna at the Globe & Mail, hoping that he will update us. He can get qualified opinion, and that would be very helpful. We need to know whether all pensions are exempted, both defined benefit and defined contribution plans, RRSPs, RESPs, etc. It looks like they are all exempted, but I am not a lawyer or tax expert.
