My financial goals came from saving money, reducing costs and having a basement suite. The suite provided additional income - and yes, I reported the income - that was used to accelerate mortgage repayment. 

It saddens me that a couple decades later, young responsible people, may find doing this can have a very negative impact on the personal residence capital gain exemption. The new rules will remove that part of a home from the exemption. So a person(s) with a small bungalow that gave up their basement to make ends meet, may be faced with a tax bill - far greater - than the rent collected.
