It's important to note, I think, as I believe I may have mentioned earlier, that in terms of these amendments, they will be reflected in an individual's tax return that gets filed for the 2021 taxation year. There's no administrative action that the CRA really needs to take until it starts looking at those tax returns well into 2022. There's a little more time for the CRA than having to administer or assess right away. It's important to keep that in mind.
It's often the case that amendments might apply as of a particular date or to a taxation year. Amendments that apply as of a particular date are typically transactional in nature. They might apply where you sell shares, pay a dividend or make a particular type of investment where you can pinpoint with specificity when that transaction occurred and what day it occurred on. That's typically something that we would look to in developing measures and making recommendations on the effective date.
For rules that affect the computation of income over a period or taxation year, where they can't be tied down to a specific transaction that occurs on a specific date but rather apply throughout the taxation year, then I would suggest that application dates that apply as of a particular taxation year make a lot more sense. It really depends on the measure and providing the application date that works best and gives the most certainty to affected taxpayers.
