I am in the GTA. I am not going to raise my fees until the new Bill comes but that is because I am at the top end for my area.

Based on the $45-50 for your area. If you currently charge $45 then I would raise it to $50 if you can get it. You don't even need to mention the Bill for your fees. This is what your fee is in the New Year. If you are already at the top end of your market then I would keep your rate at the current rate and raise it in 2016 and when you give notice of the raise, give the Bill as the reason.
