TORONTO -- The Toronto Argonauts signed York University offensive lineman Chris Kolankowski to a contract Wednesday.

The Toronto native, who was drafted by the Argonauts in the sixth round of this year's draft, started all 16 games over his final two seasons at York.

The Argonauts also signed Canadian receiver Malcolm Williams, kicker Ryan Hawkins and offensive lineman Brandon Washington, the team said in a release.

Williams, a native of Maple Ridge, B.C., spent last season on the team's practice roster after playing three seasons with the Canadian Junior Football League's Langley Rams.

Hawkins, a Northern Arizona product, and Washington, who played at the University of Miami, return after previously spending time on the Argonauts' practice roster.
