Answer:
they looked for new fur supplies.
Step-by-step explanation:
The French expanded the French territory of Canada to New Orleans. They built the city of New Orleans, a major trading post, where mostly timber and fur were drained, as there was no incentive for agricultural production in the French territories. This situation occurred mainly because there was no great incentive of the French crown in the colonization, being private companies the exploitation.
With this, we can conclude that the main reason for the expansion of the French territory from Canada to New Orleans was the search for new fur supplies.
