By the early 1700s the New France settlers were well established along the shores of the Saint Lawrence River and parts of Nova Scotia, with a population of around 16,000. However, new arrivals stopped coming from France in the proceeding decades, meaning that the English and Scottish settlers in Newfoundland, Nova Scotia, and the southern Thirteen Colonies outnumbered the French population approximately ten to one by the 1750s.

From 1670, through the Hudson's Bay Company, the English also laid claim to Hudson Bay and its drainage basin, known as Rupert's Land, establishing new trading posts and forts, while continuing to operate fishing settlements in Newfoundland. French expansion along the Canadian canoe routes challenged the Hudson's Bay Company claims, and in 1686, Pierre Troyes led an overland expedition from Montreal to the shore of the bay, where they managed to capture a handful of outposts. La Salle's explorations gave France a claim to the Mississippi River Valley, where fur trappers and a few settlers set up scattered forts and settlements.
