This is probably a basic question but I am getting confused by articles on the net. Where can I find (or how to calculate) the sum of my RRSP contribution room from years past where I did not contribute up to the max? My notice of assessment gives me a figure for my total contribution room for the next tax year, but this does not seem to include previous years room.
For example, I have been contributing about $5000-10000 per year for the last 5 years, but usually would have about 10-15k more room. So it seems I should have at least $50000 contribution room from the past 5 years, but my notice amount is for $40k.
Do I have to go through all my past year notices and add up the leftover contribution room? Does the room not carryover indefinitely?
