in New France. He arrived in New France in 1683 as a soldier and surveyor and participated in several campaigns against the Iroquois and the English.
After converting to Catholicism in 1687, he obtained the rank of officer and devoted himself to surveying and building military and civilian works. In 1700 the Sulpicians, seigneurs of Montreal, commissioned him to dig a canal to Lachine (Lachine Canal), but technical difficulties prevented him from completing this task. Appointed lieutenant in 1704, he surveyed the colony's seigneuries, then drew up plans for Montreal and participated in the construction of its fortifications. Between 1707 and 1710, he produced maps of the governments of Quebec, Trois-Rivières, and Montreal with a level of detail unique under the French regime. This work made it possible to better plan the development of the colony, particularly from an agricultural point of view. From 1720 he worked on Île Saint-Jean (now Prince Edward Island) and then obtained the rank of captain (1723) with a company command at Louisbourg.
