I was driving home from work yesterday afternoon, listening to Dave Naylor on TSN radio.
He was relating a story that a while ago he received an email from a listener who provided a link to the minutes of a Toronto city council meeting. In those minutes there was a discussion about the building of BMO field. Apparently, a condition of the city financing this facility was that it be amendable for CFL football, and the Toronto Argonauts being able to use it. Approval was passed based, among other things, on that promise.
When Naylor followed up on this new development with a city spokesperson they told him essentially, it can be used for football, if they knock out the end zone and extend it. Needless to say, Dave didn't find that idea very economical or practical.
