Some notable ones include a coal miners strike that resulted in the Estevan Riot in Estevan, Saskatchewan that left three strikers dead by RCMP bullets in 1931, a waterfront strike in Vancouver that culminated with the "Battle of Ballantyne Pier" in 1935, and numerous unemployed demonstrations up to and including the On-to-Ottawa Trek that left one Regina police constable and one protester dead in the "Regina Riot."
