Participants include: Environmental Defence Canada, Sierra Club Ontario, Ontario Sustainable Energy Association (OSEA), CPAWS Wildlands League, and Canadian Association of Physicians for the Environment ( CAPE) with more organizations expected to join the ComeClean campaign. Clean water, good green jobs, dirty coal, Ontario's greenbelt are among the issue area identified to track so all politicians and candidates will come clean about the environment during Ontario's upcoming election.

Many environmental expectations publicized during Ontario's last election were endorsed by the McGinty Liberals in Ontario. The McGinty government has acted on certain of these endorsements, while others are delayed, or subject to confusion. Among these problematic commitments is the public promise to protect at least half of Ontario's boreal regions, and to support First Nation community lands planning including for identification of lands for protection from industrial uses.

The ComeClean web site hosts videos, and a sign on in preparation for the Ontario election.
