The most complete maps of Canada are the ones issued by each province.
No commercial map will ever show all there is to show or be up to date. I remember one situation when I worked in Corner Brook and some rvers came to see me. I sent them via a new road which had replace a former railroad track. Their information had nothing about it and sent them a wierd wierd way.
Then I remember having a friend connecting with me in PEI and got one of these on dash things. For a province with a lot of interesting rural places??????????? Do those things think people want to explore historic villages? Seldom.
So, go to www.google.ca , yes, .ca because that's Canada domain and brings up things Canadian over other countries. Search 'name of province and tourism' for each province you may visit. Calling gives you a chance to bring out your special interests. A make sure to ask for a map.
All Canadian provinces have lots of interesting rural features. You find many of these by talking to locals ---- including at grocery stores. When your on a seacoast, 'where do we get the best fish?', 'what is your favourite lobster restaurant?'. 'Is there a place where we can eat lunch and watch whales'?,
& don't forget the visitors centers.
