I wonder -- does the increased amount of child tax credit (Ontario) that I will receive once I'm filing income tax on my own (will go from $68 to approx. $190) get calculated into the support settlement? My ex and I had previously agreed to a specified amount of support, plus he would pay for half of any extra-curriculars for our daughter. Now, he's discovered that the child tax credit will increase for me eventually, and says that extra $ should mean he pays less.
