Reddit user (UnfazedButDazed... great name) says they have been working on a site that will alert you once Alberta campgrounds open up!

He claims he has seen positive feedback with the same system in BC. If you would like to use their program follow the link to this website here: 

Once entered the website will alert you via email when your specific camp site is available.
