CFL Commissioner Stewart Johnston says Quebec City has emerged as the leading candidate for an expansion franchise. Johnston made the comments Friday morning at his state of the league address at the BMO Centre in Calgary. He said the CFL has had substantive conversations with a prospective owner in the Quebec capital. “Quebec City is the leading contender for the 10th franchise,” Johnston said. “I understand there is significant speculation. We want to make sure that all our ducks (are) in a row. That there’s still a lot of work to be done in anticipation of what a franchise could look like. There are no guarantees.” Johnston declined to identify who’s in the talks, although real estate developer William Trudel has spoken to Quebec media about his interest in a CFL expansion club. Johnston wouldn’t say if, or when, a Quebec City franchise might be up and running.
