On the 17th of July 2010 only, Parks Canada is having a free day!
On that day, access to all their national parks, national historic sites and national marine conservation areas is totally free!
This could be the perfect excuse to pack up a yummy picnic, load the kids in the car and see where you can visit.
I am posting this well in advance, and I will bump it up closer to the date in question! I recommend you make a note in your diary now... so you can plan ahead!
