hockey stadium in toronto is shared with basketball.
football stadium in toronto is shared with baseball ( or vice-versa ).
its only fair that BMO field do what the argos want them to do, since the stadium was originally pitched to politicians as a potential home for the argos...this is what helped get them the funding in the first place....once they secured the funding, they changed the design without knowledge or support of those who granted the funding.
if BMO does become home of the argos, MLSE should be footed the bill to change the stadium back to the original design which they were approved for..which was CFL field size.
any further expansion of the stadium, to 35K, should be split between the argos and MLSE.
