This is the nearest LCBO to me, so I go there often. The selection can't compete with Summerhill, but generally it is fine and I can usually find what I want. They have a Vintages section.
One thing to watch out for is one clerk, tall bald guy named Paul, who is very anal retentive, and he usually will not serve you if you've even got a tiny whiff of alcohol on your breath. I had just come back from a friend's birthday brunch on a Saturday, and I was refused by him when I was not in any way impaired. Most of the staff there are very friendly and accommodating, though.
