Section 147.4(1.1)(b) of the Local Authorities Election Act requires municipal candidates to clear any campaign deficit if they are not running in the next general election.
Any Candidate who runs a deficit during the 2017 Election can fund-raise between now and the end of the year (December 31, 2017) to reduce the deficit. Those contributions are considered to be part of the 2017 election campaign contribution disclosure due on March 1, 2018. The contributions are subject to the limitations set for the corresponding campaign period. (For example, Alberta resident can contribute $5,000 per calendar year or $10,000 limit to the candidate)
After December 31, 2017 if the candidate has a deficit they can file a statement indicating the deficit.
Following January 1, 2018, and upon registering to collect campaign contributions, they can continue to fund-raise to eliminate the deficit before the next election (October 2021) subject to the contribution limits. The candidate must eliminate the deficit.
On or before March 1 immediately following a general election or, in the case of a by-election, within 120 days after the by-election, if a candidate's disclosure statement shows a surplus, the candidate shall pay the surplus to the municipality.
Section 147.5, Local Authorities Election Act
Return of the surplus to the candidate will be on Nomination Day 2021 when the candidate files nomination papers.
