Quebec to Detroit to Wisconsin

My great-grandparents and grandmother came to Quebec 04 June 1871 after leaving Bergen 23 May 1871 on the Frigate Bird. Johannes and Oline Bjorlo with 2 children. On Johannes' naturalization papers in states that he came into the port of Detroit. Does that mean that they boarded a different ship in Quebec and came through the Great Lakes to Detroit. From Detroit would they have taken a train to La Crosse, Wisconsin? Would the Erie Canal be a possibility? Thank you, Mary
