This place is AWESOME.
You pick the price level you pay for the tour. We did the cheapest "souvenir tour" for $10 that allowed you to pick between a glass or a bottle opener at the end of the tour. I was expecting we'd get the sample glasses, but we actually got full sized pint glasses! Not bad considering for $10 we got a bottle of beer, samples, glass/bottle opener, and a tour.
The tour was definitely interesting and our tour guide was knowledgable. She gave us a beer fresh off of the bottling line which was awesome. You also get beer samples right when you walk at the beginning of the tour and at the end of the tour if you like.
The brewery is located right next to the Rogers Centre, CN Tour, and the Aquarium so you can easily plan a whole day down there.
And fellow non-Canadians are probably wondering, how is the beer? It's pretty good! My dad who pretty much exclusively drinks IPAs and craft beers even enjoyed it.
