"National Parks are some of the most beautiful places on Earth. They offer a chance to escape the hustle and bustle of everyday life and to connect with nature. And they're right at our doorstep, waiting to be explored. Whether you're looking for a place to go for a hike, a picnic, or just a walk in the woods, there's sure to be a park nearby that has what you're looking for."
Obviously, they've got info on parks world-wide. But here's their page on Canada.
