What are the rules about contributions to registered third parties?

Contributions by corporations and trade unions to candidates are banned. Corporations and trade unions can contribute to registered third party advertisers. Contributions cannot be made or accepted unless the individual, corporation or trade union is registered as a third party and can only be made during the campaign period (which begins the day the third party registers and ends on December 31, 2018). Money, goods and services are considered contributions.

The maximum contribution from a single contributor is $1,200 to a registered third party advertiser and a total of $5,000 to two or more registered third party advertisers in a municipality. These limits do not apply to contributions by a registered third party advertiser to itself and, if the registered third party is an individual, by his or her spouse.
