In 1935 , the RCMP , collaborating with the Regina Police Service , crushed the On-to-Ottawa Trek by sparking the Regina Riot , in which one city police officer and one protester were killed . The Trek , which had been organized to call attention to the abysmal conditions in relief camps , therefore failed to reach Ottawa , but nevertheless had profound political reverberations . The RCMP also lost four officers in Saskatchewan and Alberta that year in what became the 1935 Royal Canadian Mounted Police Killings
