Parks Canada says visitors will be able to start booking reservations for camping and other activities at its sites across the country in March.
The reservation dates, which are posted online, are different at each national park, historic site and marine conservation area.
Parks Canada says in a statement that the bookings are a couple months later than recent years because the reservation system was getting outdated and needed some upgrades.
The agency says the system will look different from the previous one, but it will offer the same features and functions.
It adds, however, that anyone who wants to save information about previous bookings to do so before Feb. 26.
All users will be required to create a new user account on the upgraded system after March 3 and before they start booking any reservations later that month.
