My go to place for getting a massage in Calgary. It's a bit out-of-the-way but still inner city. It's a large facilities that multiple RMT's over the entire week and many slots. I've been able to get appointments when I called in the same day sometimes.
Massage therapists very by person but in my three years of coming here, I've never had a bad RMT. I have my favorites and I go to them and I suspect you will as well once you get a massage here.
