Registered_third_parties_(Canada)
In Canada, a registered third party is a "a person or group that wants to participate in or influence elections other than as a political party, electoral district association, nomination contestant or candidate." Third parties register with Elections Canada and are regulated under the terms of the Canada Elections Act.[1]
Third parties are subject to different regulations for campaign and pre-campaign periods. There are no limits to what a third party can spend on political advertising pre-campaign — spending rules are only in force once the writ is dropped and the campaign has officially begun. A person or group must register as a third party immediately after incurring election advertising expenses totalling $500 or more.[1] There are strict limits on advertising expenses, as well as specific limits that can be incurred to promote or oppose the election of one or more candidates in a particular electoral district.
It is illegal for a third party and a registered political party or a candidate to collude with each other for the purpose of circumventing the maximum amount that a registered party is allowed for election expenses.[2]
