The Internet can give you a lot of information with regards to where to go.
It is understandable for a tourist not to know the best places so it is always recommended to search ahead of time so that you do not end up getting lost while you are out exploring different places.
Though if you are brave, you will allow yourself to get lost, because that is part of being adventurous as a traveler.
Join a tour group
For any tourist, it is always better that you join a tour group because these programs will already have locations in mind, itineraries, and basically everything all figured out and fixed before you start exploring Canada.
Ask friends and family members
Chances are your friends and family might have already visited Canada before you. You can always ask them for a recommendation on where to go, so that when you get there all you have to do is find it.
