The 2008 TSC Stores Tankard, the Ontario men's curling championship, was held February 4-10 at the Waterloo Memorial Recreation Complex in Waterloo. The event featured 11 teams, instead of the usual 10, since the Glenn Howard team was granted an automatic bye for having won the Brier the previous year. Team Glenn Howard would repeat their third straight provincial championship, defeating 2000 champion Peter Corner in the final.
