1) There is no limit on the amount of current year tuition fees tax credit that can be transferred to a spouse.

It's false, right? Maximum should be 750$

2) Refundable credits are only paid to the taxpayer if that individual taxpayer has a tax payable balance.

It's false right? I'm not sure about this. If they have tax liability > refundable credits, refundable credits will also be applied to reduce tax liability.
