That one I can handle a little more quickly because I recall the particular circumstances.
The Tax Court of Canada, in a case called Otineka--the name's much longer than that, but it goes by the short name of Otineka--in 1994, came to the conclusion that a municipality, for the purposes of determining whether a wholly owned subsidiary corporation of a municipality could be tax exempt.... It took the position that a municipality could be determined such or not such based on the functions the particular entity exercised. In this case it had to do with an Indian band, as to whether they qualified as a municipality and were therefore eligible to have tax exempt municipal corporations.
The Income Tax Act was administered on that basis for some time, until another decision came down, Tawich Development Corporation v. the Deputy Minister of Revenue for Quebec, which came to a contrary conclusion. As a result, you now had a situation where some municipalities or some entities that thought they were municipalities--Indian bands or otherwise that were treated as municipalities based on the functions they performed--might not now qualify for that, and therefore their wholly owned municipal corporations would also not qualify.
The amendment here fixes it to reinstate the status quo ante such that the determination of whether or not an entity is a municipality or not for the purposes of being able to have a tax exempt municipal corporation as a subsidiary is determined based on the functions exercised by the entity.
