I'm in Calgary and although rates vary from each area, I have never seen a day home charge that much. I have typically seen anywhere from $35-$40 per day, roughly $700 - $800 per month... a few more dollars per day for part time.

That being said, if you are filling spots and are finding parents are okay with what you charge, keep doing what you're doing. If you're having a tough time filling spots, I'd lower it some.
