I doubt it sells out at Toronto prices. It is not just the cost of tickets, it is the cost of everything at full Leafs prices.
And no region is the heartland of Hockey. Saskatchewan may produce the most per-capita, but Toronto produces more NHLers than anywhere else. Just look at the amount of stars who played in Toronto youth leagues at somepoint. McDavid, Stamkos, Tavares, Pietrangelo, Subban, ROR, Seguin, etc.
I'm sure people would be lining up in the praries to see nothing games involving Canada at a venue that charges 12 to 18 dollars a beer and crazy food prices. I went to USA vs Slovakia yesterday and spent more on concessions than I did on the actual ticket.
Also realize we have had the WHC and the upcoming Centenial Classic which have taken some of the money people would allocate to the WJC.
