Answers are going to vary. You can be from gate to curb in 40 minutes or in can be 2 hours. It can depend on what time of day, day of the week, customs or even the terminal. I've travelled a fair bit in the last year and would say that it's no different than it has ever been. My last trip flying in to YYZ in February, the bags took about 20 minutes from the time we arrived at the carousel. My DD has been back and forth several times to the US over the last few months her experience has been 20-40 minutes waiting at the carousel.
