I also had the unpleasant task of finding a family doctor in Calgary upon moving to the city a few years ago.
The first doctor I picked off the list was absolutely horrible. I picked a new one based on feedback given on the Rate MD's website.
As with any feedback sites, take the comments with a grain of salt but I'd think that most folks would have similar heathcare expectations.
Nevertheless this site might be useful to help narrow down your search!
