These time are realistic iff you are travelling with US or Canadian passport; otherwise leave more time.
You might also have to deal with check bags for you will be entering Canada and not transiting to US direct.
That's a good point. I will be travelling with US passport. So do you think if I realistically only have 1 1/2 to 2 hours I could see anything in Vancouver? Isn't there a place to store or check my carry on (in YVR) while going on this quick outing before my next flight?
