Believe it or not, the NFL is the
2nd-most followed league in Canada, behind the NHL of course. Some statistics from last year show that the NFL is making
serious inroads in Canada especially with younger generations and in eastern Canada, eclipsing the CFL in popularity. Anecdotally, lots of people I know watch the NFL. We are a Lions household over here and we started following more intently this year. I know lots of people that follow various other teams as well (Bucs, Bears, Seahawks, and lots of other Lions fans), but no Bills fans funny enough.
As for hypothetical financing of a team/stadium, I could see it done without any public funding. MLSE is now worth $12.5B CAD, and will most likely be valued even higher once Tanenbaum gets bought out in 2026. A future IPO of 49% of the shares (leaving Rogers with 51% controlling ownership) would probably fetch enough money to cover an expansion fee and maybe a portion of stadium construction. Nobody really knows what the expansion fee would be at this time, but it was pegged at a suspected $3-5B USD in 2022 (probably ~$5B now given the rough median NFL team valuation).
To top this all off, someone even asked Doug Ford at the
press conference earlier about the suitability of Downsview for the NFL and said “I believe so”, not that it necessarily means anything though.
