The U.N. estimates that there are about 65 million refugees in the world today.  Any attempt to resettle a few refugees into the U.S. (or into Canada for that matter) isn't really going to make any difference because of the vast size of the problem.  What would make a difference is to stop creating the conditions which produce large numbers of refugees in the first place.  Trump was not in office when the conditions for producing masses of refugees came into being.  Probably the best thing he can do for refugees is to promote a wind down in the wars in the Middle East.
