Should I make reservations now for Nova Scotia, etc?

Not sure about NS but here in Ontario people sit on their computers 5 months in advance at midnight when the reservations open to get campsites reserved in Ontario provincial parks and they are gone in a day or two. I tried reserving a national park campsite in Manitoba when reservations opened and because I waited until the second day the reservations opened I couldn't get a reservation for the dates I wanted.

Bottom line - reserve ahead to be sure that you can get in, and do it early!
