The CFL club will have to play its Oct. 6 home game against the Redblacks in Ottawa because the Jays could be playing in the American League wild-card game that day at Rogers Centre.
And more changes could be coming.
The Argos, whose home schedule has already been heavily impacted by this summer's Pan American Games, have four more games at Rogers Centre in October.
Should the Blue Jays reach the World Series, the Argos' games Oct. 17 (versus Calgary) and Oct. 23 (versus Montreal) could also be relocated.
Toronto's home game against the B.C. Lions on Oct. 30 will go as scheduled.
The baseball playoff schedule is already set and controlled by Major League Baseball.
The Argos are in their final season at Rogers Centre and will move into a refurbished BMO Field in 2016.
The Pan Am Games forced the team to play its first five games of the season on the road, including the home opener against Edmonton in Fort McMurray, Alta.
