France expanded its control in North America in several ways. One way that France expanded control is with the courier de bois, who made ties with the natives, from trading furs, and expanded the land deeper into Canada. This land, however, needed to be secured, and populated, and that was done with the seigneural system, where farmers would live on and work the land, and furthermore, infrastructure such as tanneries and breweries were established, these buildings and farms made use of the land, and reinforced it as well as increased population density because farmers who settled would have children who also farmed. Jean Talon was one of the main contributors to New France’s population density as he encouraged them to be self-sustaining and not just to hunt for land that they can’t defend.
