The Toronto Argonauts selected Mike Bradwell, a Leaside High School graduate, in the 2008 CFL Canadian Draft.
A CIS All-Canadian wide-receiver, Bradwell holds McMaster's all-time school record for receptions in a season with 53 in 2007.
He was a multi-sport athlete when he attended Leaside and also excelled at hockey.
"We're extremely excited about the prospect of Mike Bradwell joining the Argonauts family," said Greg Mohns, Argonaut's assistant general manager and director in a release.
"He is a talented, athletic receiver with outstanding size and speed. We feel he will blend in nicely with our existing Canadian talent at the receiver position."
