I don't know about Vancouver, but going through US customs/security in Toronto is a major PITA (upwards of 3 hours standing in unending lines). That's why I will always choose to NOT transit through the US if at all possible, unless, of course, I'm actually going to the US or departing on a cruise in Florida.
Just my personal preference I guess.
