^And a ridiculous number of F-Bombs from the linesmen at the end of regulation time...
That said, I also think there is an underlying interest in USports and such... It's just that it's not at all easy to get info/watch it. Games generally aren't televised (other than perhaps a local cable feed) and the main media pumps the NCAA and doesn't give any time to Canadian University sports other than a perfunctory "x won the Vanier Cup, now onto this week's NCAA matchups".
This is where I think the CBC might really have an opening for what they do. The "competitive" media, especially in English-Canada do an atrocious job covering Canadian sports, and instead focus on being a relay for American sports/commentary (mostly why I've almost entirely tuned out of sports over the last number of years).
It could be helpful if the CBC launched a pure sports channel and they only showed USports, Junior football, some CHL if possible, world tour international competitions featuring Canadians, etc.
And the Vanier should generally be bundled with the Grey Cup for a Football weekend (other than a few 1-offs at decent sized stadiums once in a while, e.g. Laval... though it would be easier if QC eventually turned their attention to getting a CFL team instead of chasing the NHL, which seems to only care about their US $$$ dreams). Could be interesting to bundle the CJFL championship in there too, but that happens a little earlier and Quebec/Atlantic Canada isn't in the league.
