The Missionary Oblates of Mary Immaculate
Arriving in Canada from France in 1841, the Missionary Oblates of Mary Immaculate have ministered from the Atlantic to the Pacific, and in the far North. "Missionaries to the Poor", they followed the explorers and settled in the remote outposts of the colonies and in the villages of the aboriginal peoples whose languages they learned and customs they studied. The Oblates established parishes adapted to the culture of the people and set up educational institutions where instruction is offered in Canada's two official languages. Their works have made a significant contribution to Canadian ethnography.
