It's downtown.
Has many maps of crown land, has landowner maps that list each and every landowner in the area. Has topo maps of the area, pretty much anything you could be looking for.
As for online, I tend to use proprietary mapping software, so I don't know what's available in the public domain, but I'm sure there is something. In the meantime, paper maps will cover you.
There is a lot more mapping out there, though. I mean, you are a landowner, right? Wouldn't you want to know what you own?? The Alberta Geological Survey, the Geological Survey of Canada, and others, have maps of your land showing a lot of interesting stuff. Check it out.
