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.
Toronto Maple Leafs played at Maple Leaf Gardens until Feb 1999. The PATH was created before then.
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. :)
I should clarify I was told this by a guy who lives in Montreal, who apparently was retelling the story he heard from a guy who lives in Toronto with minor editorializing.
The Habs lost their way much earlier than that. They were the cultural identity ~50 years ago. They instigated a revolution. Nowadays they're just a cog in an American empire.
Tbf it said could, not would: the potential for watching the win is what entices; without game fixing it'd be good sportsmanship to not shit on a person's favorite if one wants anything from said person.
