CFL Commissioner Ambrosie has broached the idea of moving the start of the season earlier so that the Grey Cup is played in October.

There are a lot of moving parts to the argument both for and against moving up the CFL schedule — tradition, cold weather, snow, competition with the Stanley Cup playoffs, competition with the NFL, etc. — but there’s really only one factor that matters to the CFL office: money.
The CFL has been selling its American television rights to ESPN for a paltry sum for close to a decade now. Former commissioner Mark Cohon — the man who made the first ESPN broadcast agreement in the late 2000s — didn’t see the deal as an opportunity to make money, but as a chance to gain exposure south of the border. Now that the CFL is getting a fair amount of attention from an American audience, it may be time to capitalize by negotiating a more lucrative broadcasting agreement. ...

More and more Americans take an interest in the CFL every year for a number of reasons. For one, many big-name college stars who end up in the CFL bring with them legions of fans who want to follow their careers through the pros. Players like DeVier Posey, Trent Richardson, Darvin Adams, Tommie Campbell, and James Wilder Jr. all come from huge football schools with massive fan bases. Seeing former college stars enjoy professional success in Canada should only turn more American fans onto the Canadian game.
Secondly, the CFL is phenomenally entertaining — I’ve been following it and the NFL for almost twenty years and the 2017 season was as compelling a campaign as I’ve seen north or south of the border.

IMO, this would run into the Argos overlapping with the Blue Jays at home and on TV for nearly all of the CFL regular season, and even more important with the NHL playoffs on TV virtually every day in the early season. Argos media exposure would suffer even more in this regard if the Leafs play far into the playoffs. This is likely to reduce the already low level of attention the Argos achieve in the Toronto media and TV viewership of Argo and other CFL games, thereby reducing revenue from a fall in attendance and eventually from a dropoff in Canadian TV ratings that would result in less money in a future Canadian TV contract. While an earlier start would earn more NFL money, I doubt this will be a bonanza, especially at the beginning, when the league has not proved yet whether it can grab a large American viewership with an early start. Neither NFL Europe viewership on American TV in the spring or CFL expansion into the U.S. caught on in a significant way.
