Also in Manitoba here. I personally think you need to charge similar to those around you. You have to remain competitive pricewise no matter what you are offering as perks.

You could also start advertising at that price and see if you get any interest. The problem is though that you might scare people away and even if you lower your price eventually you might miss out on some great families.

There are tons of things that can be written off come income tax time so in the end it all works out IMO.
