First timer on Air Canada coming up, couple of questions. 1). Headed up to YYZ from IAD. I have a 7 hour layover on a Saturday, any chance it is enough time to get out of the airport (huge hockey fan, would love to hit the HOF if possible)? 2) Heading to ZHR in business, basically looks like Virgin's UC offering, is this about what I can expect? 3). If stuck at airport, which lounge would you hit, or how would you kill 6/7 hours.

Thanks!
