Googling is indicating Fontana is maybe in Toronto. True? If so, there is a cool brewery there called Mill Street. My gf and were there a couple years ago and we tried a few of their beers before going on a tour. It was just my gf and I on the tour and we said we were homebrewers and she asked what we thought of their beer and we said that in general we liked hoppier beers than what we had from them. So she went to the cooler and gave us a growler that she said we'd like. I asked how much and she just said to take it. Very cool of her to do that. We were driving across the border and I was worried about taking it across, but of course we had no issues. And she was right, it was a very good beer.
I've also heard that Flying Monkey's makes some good beer. I've only had their Netherworld black IPA, but it was very good.
Other than that, I don't remember anything else except the poutine was freaking awesome!
