When I am trying to plan a trip from Alberta to Ontario, google maps keeps switching my route to go through the United States. When it initially shows the different route options, I select the one that does not detour to the United States. Yet, every time I add a stop along my preferred route… For some reason it keeps switching it to go through the United States. Is there not a setting that I can select to prevent it from making me go through there? I just want to see Canada on this trip.
