Following his graduation from the University of Western Ontario, Taras was drafted by the B.C. Lions in the third round of the 1987 CFL Draft as a guard.[5] Taras initially played fullback for the Lions for four years, but achieved the greatest success of his playing career as an offensive guard, and later, center.
In 1994, Taras was a part of the Lions' 11-6-1 season that culminated in a Grey Cup matchup with the Baltimore Stallions. The Lions ultimately prevailed, 26–23. The following season, 1995, Taras, playing guard, was named a CFL All-Star for the first time. Taras would be named a CFL All-Star a second time, in 1999, for his play at center. Taras twice won the DeMarco-Becket Memorial Trophy as the CFL Western Division's Most Outstanding Lineman, in 1995 and 1999. In 1999, Taras was also awarded the Dr. Beattie Martin Trophy as the Most Outstanding Canadian in the CFL Western Division, and the Tom Pate Memorial Award, for his outstanding sportsmanship and service to the community.
In 2000, Taras was a member of the Lion's fourth Grey Cup championship team. The Lions defeated the Montreal Alouettes 28–26, with Taras snapping the ball to then-Lions quarterback, Damon Allen.
Taras retired from the Lions in 2003, and was voted a member of the B.C. Lions All-Time Dream Team, at the guard position, as part of the club's 50 year anniversary celebration.[2] Taras #60 was also retired by the Lions, but curiously, his jersey number was worn during the 2006 CFL season by then Lions tackle, Jason Jimenez.
