Oblates begun their permanent ministry among Inuit in 1912. In the beginning it consisted in continuous traveling between single camps in the vast area of the Arctic and in this way reaching the people with the Gospel's message. Slowly the missions were constructed, mostly close to the trading posts, where Inuit were gathering after periods of hunting and trapping.
Today there are 16 established missions in the Diocese which covers almost whole Nunavut. Oblates are divided according to the needs of particular regions. Each missionary has main place where he resides and from which he visits from 2 up to 5 others missions. Oblates colaborate strictly with local leaders and other pastoral workers. Local leaders are fully responsible for the rhythm of prayer and other pastoral services in the communities in the absence of a priest.
