TO is always sold out even though they stink.......it's hockey in Canada needless to say
I went during the summer, I didn't see the Maple Leafs. If you mean tickets to Toronto itself, I bought a Flight + Hotel package for 8 days at Novotel Toronto Centre (AWESOME hotel) with the city pass included (allows you to see all the Toronto attractions for one combined price) on Expedia.com, for around $795.00
It was well worth it. HHOF is awesome, as is the CN Tower. Across the street from the HHOF is this awesome bar/restaurant called Shopsys. BARBECUE BEEF SANDWICH AND A 20 oz. HOEGAARDEN. Nuff said.
