Adrian Cann was signed by Toronto FC on April 12, 2010 after a successful trial with the club. He made two appearances with the Reds in preseason and impressed sufficiently enough to earn a contract.
Cann was drafted 16th overall in the 2004 MLS SuperDraft by the Colorado Rapids and made just two appearances. Released midway through his first season he moved to the USL First Division and signed with the Montreal Impact making a total of 22 appearances. From there he moved west to the Vancouver Whitecaps and signed with them in 2006. He made 58 appearances for the club and was awarded the “Most Outstanding Defender” in 2007.
Before returning to Canada to join Toronto, Cann spent two seasons playing in the Danish league with Esberg FB.
