The Canada Elections Act stipulates that candidates must be eligible electors. In order to be an eligible elector in a riding, you must be "ordinarily resident" in that riding. To my knowledge, Ignatieff disqualifies as an elector, and thereby as candidate, in Etobicoke-Lakeshore for the following reasons:
- Ignatieff has no known connections (dwellings, residences, etc.) in that riding. He has not lived there before.
- Ignatieff does not intend to stay in that riding if he loses the race. That is, he has indicated that he would return to Harvard if he lost the election. In order to qualify as being "ordinarily resident" one has to fulfill this demand as stipulated in the Act: "The place of ordinary residence of a person is the place that has always been, or that has been adopted as, his or her dwelling place, and to which the person intends to return when away from it." Thus, the only concievable way that Ignatieff can be considered ordinarily resident is if he bought some property and intended on residing in that riding. But since his comments in the Harvard Crimson do not show he intends to permanently adopt it, or return to it "when away from it", Ignatieff has disqualified himself from being an elector in that riding.
But this is purely my opinion. There be facts of which I am unaware.
