This category is for people who emigrated from Canada to the United States from about 1780 until confederation in 1867. It should be limited to people who emigrated to areas that were then under the control of the United States. It should be limited to areas that were then designated as Canada as well. So in 1865 it would cover people coming from Canada East and Canada West, but not those coming from other areas under British control. Those coming from other areas then under British control would fall under the Emigrants from the British Empire to the United States or another appropriate sub-category.
