They do get likely 10% for the Superbowl atleast.
the thing is the amount of Football fans in Canada wouldn't really grow.
There already is 5M football fans in canada, 10% of the canadian pop is 3.2M ish.
so they might get 3.2M, compared to in the states with a team your limited you are looking at the local area.
Now if you compare 1 City vs. another City. Toronto is the 5th largest North American City.
So if your looking for ratings, there is no way Toronto or Vancouver if Drawing 10% of their pop would get lower Ratings then say Green bay, if your only looking at the pop of Cities.
Both Vancouver and Toronto are in the top 32 Cities of North America(population wise)(Montreal too)
so looking at those Cities in terms of population makes sense no?
Why would people Tune in to Watch Jacksonville vs. Green bay?
Nashville vs. Buffalo?
Kansas City vs. Carolina?
those aren't huge population wise.
New york vs. Toronto however is two of the largest Cities by population.
Or Detroit vs. Chicago
Detroit, Chicago, Toronto, Philly, New York, LA, Miami, Dallas. Just going by Pop should equal huge ratings.
I don't think they will get huge support in canada, but the NFL looking at canada has got to see alot of potential, 30-32M people, that is enough pop to support say.. 4 NFL teams.
Starting off with 1 in TO for them makes sense, look at the amount of money the NHL gives per year for hockey(100M$) so that is enough for atleast 1 team. and the ability to have american teams beat up on Canadian teams would be good for the NFL ratings.
BC + alberta + Ontario + Quebec.
I'm not saying it would fly, but the NFL might try to get into canada.
