I can't enter ON Provincial tuition transfer amount from 2 dependent children as prior years using forms; no field for the Provincial portion, only Federal. 2018.

Unfortunately tuition transfers are no longer available, for the provinces of Ontario and  Saskatchewan for 2018 and New Brunswick as of 2017. Tuition is no longer a credit for students in those 3 provinces so there's no money to give. For this reason there is no longer any Provincial area to enter the tuition transfer amount as you seen in previous years.

Thanks for the detailed answer. Very helpful.
