On March 22, 1836, he and 15 other French Canadians on the prairie representing nearly 80 settlers and their children signed a petition to Norbert Provencher, the Bishop of Juliopolis, requesting a priest for the settlement. At that time of this petition, Belleque had three children. In 1843, at Champoeg, Belleque participated in the debates over whether the settlers in the region should establish their own government, or wait until the Oregon boundary dispute was settled. At the final vote on May 2, 1843, Some of the French Canadian pioneers voted against forming a government. However, the measure passed by a vote of 52 to 50 at the Champoeg Meetings, and a provisional government was created.
