Here it seems a bit much to invest a few thousand dollars plus the monthly opex to have your home 2-3 degrees cooler on the 5-6 days a year where we are at or around 30 degrees. The nights always seem to drop down to 10-12 degrees even on the hottest days, providing a nice natural cooling breeze.
What would someone expect the average monthly cost to run a CAC system in a typical Calgary house be from June-Sept?

Depends on the orientation of your house, how much shade it gets, and how sheltered it is from breezes. I've had houses where you absolutely didn't need AC, and houses where it was on almost daily April - September. I keep it at 22 degrees - without it my house could be 28+ through much of the summer. That's not a couple degrees five or six times a year.
Your house must just be fine. It's not because you've lived in warmer climates. You have acclimated back to Canada by now if you've been back for more than a few months.
