Well, I just switched my Travel Infinite card to the Aeroplan Infinite. They converted my 6k points to Aeroplan at a 4:1 ratio.
FYF and 15k miles is nice. If they don't waive the fee next year (I have the All Inclusive account), I'll cancel.
I only use my Canadian card when I'm in Canada (that way I deal with currency conversion on my own terms), so it won't get too much use. It's nice to know that I'll have trip delay protection on my Canadian card though.
