The Doer government announced election spending reforms in June 2000, which were highlighted by a ban on political donations by private corporations and organized labour. This measure was opposed by the opposition Progressive Conservatives, and by the right-wing Canadian Taxpayers Federation. The reforms came into effect in 2001, and were extended to party leadership contests in June 2002. Further restrictions were added in 2006. In June 2009, Winnipeg Mayor Sam Katz spoke against Doer's plan to ban union and corporate donations from municipal elections.
