During Father Le Loutre's War, Maillard encouraged the Mi'kmaq declaration of war against the British.
To assist the religious efforts Maillard self-financed construction of buildings (beginning 1754) on Île de la Sainte-Famille (now called Chapel Island) in the south of Grand Lac de La Brador, where his main mission was located (he did receive a reimbursement of 3,000 French livres in March 1757) [REF].
