In 1869, the Canadian government obtained control of the Red River Settlement from the Hudson's Bay Company. The Canadian government sent an English-speaking governor to run its newly-acquired territory. But the French/Native Métis people of the area feared that the government would take their land and treat them badly.
Their leader Louis Riel and his armed men rode out over the prairie to stop the governor from arriving. They built a barricade -- in French, la barrière -- near the village of St. Norbert. The governor was halted and sent packing back to Ottawa. This was the start of the Red River Rebellion.
Louis Riel formed his own provisional government (pictured above) at Upper Fort Garry (now Winnipeg) and ultimately negotiated the Settlement's 1870 entry into the Canadian Confederation as a full province called Manitoba.
The barricading and successful expulsion of the Canadian government's representative is commemorated today in the name of St. Norbert's quiet and peaceful little park. I'd love to go back sometime and walk in its woods again.
