On May 17, a bill to amend the Election Finances Act was introduced in the Legislative Assembly of Ontario.

Bill 201, the Election Finances Statute Law Amendment Act, 2016, which also includes amendments to the Taxation Act, 2007, bans corporate and union donations to political parties. The legislation will also limit contributions from individuals, limit spending for third-party advertising, and tighten political party spending and fundraising rules for by-elections.

If passed, the changes are hoped to be in place or significantly underway before the June 2018 election, with initial changes legislated for January 1, 2017.
