Ok got to stick my 2 cents worth in and look at this from a Ticat business point of view.
Playing in Toronto makes no business sense for the team; it caters only to the select few fans that feel a Go train ride to Toronto is handier and does 100% nothing to increase the Ticat fan base, if anything it would do more to decrease it.
Lets face it the Argo’s do not need more competition.
The Rogers Centre is not providing quality dates (days of the week) to the Argos now. What makes us think that this can work adding another football team?
How does playing there do anything for the Ticats or the CFL when the weak fan base can not fully support the existing team?
The London idea answers more questions and can help to build a stronger Ticat and CFL fan base down the road, it provides stability for the homeless season. As a bonus to the league it provides a great gauge as to the test expansion market which by population base alone has to include the London area.
One last consideration has to be the cost of erecting a temporary 20000 seat stadium at TD Waterhouse vs. the rental costs that the Rogers Corporation would want for 10 Ticat dates. IMO I think there would be considerable help from the league, the City of London as well as Western Ontario U to make the Hamilton/London Tiger Cats a great success in 2013.
London is not all that far, so many great events could be planed from car pool parades to bus trips and room for those who arrive early to meet and greet (I wont say tailgate but)
As a fan if I had a say, it would be set up in London for the entire season.
