After retiring, Heath moved to the Township of Athens, a small municipality in the Ottawa Valley. In the 2000 federal election, Heath replaced Dr. Peter Bevan-Baker as the Green Party of Canada candidate for Leeds-Grenville and received 820 votes (1.75%). The winner was Joe Jordan of the Liberal Party of Canada. Heath became president of the combined federal/provincial riding associations soon after the election. In 2003, he advocated compact fluorescent bulbs to prevent brownouts in Ontario. This idea was later promoted by provincial party leader Frank de Jong.
