I've been told the intent of the PATH was to make sure that people from Montreal could take the train to Union, walk to Scotiabank Arena and watch the Habs beat the crap out of the Leafs without getting snowed on.
Perhaps they were talking about Maple Leaf Gardens? It is a more substantial walk.
The portion of the PATH connecting Union Station to the ACC is a few hundred metres at most.
I can't see how anyone in Toronto would help people from Montreal enjoy a Habs win over the Leafs. :)
Torontonians call it the "ACC", (short for Air Canada Centre, before its current rebranding to Scotiabank Arena - Google Maps knows both). Also, it's "Skydome", not Rogers Centre. :)
Not sure how the Habs have lost their way in the past few years. First-pick of Quebec's hockey players helped a lot I guess.
