The Snow Route Parking Ban is in effect this year throughout the city so it is a great idea to check out the maps and rules so you can be prepared. It will kick in once a 'snow event' is triggered when over 5 cm of snow has fallen.
If you are looking to purchase a home, it is worth a look to see if a prospective home is on the route. The routes may change, but some folks may see the routes as a big positive or negative. You do have to move your vehicle off the road, but you will be on a cleared road and able to get out of your street after a snow event.
The best direct resource is the City of Calgary website which will have all of the latest info, link to an online map of all routes which I can't link to directly. Also check out the Road Conditions Map (SNIC) which shows up to date info across the city. Should mobility be an issue, Handicap snow route exceptions can be requested with the city.
