The Council for Canadian Urbanism has given the Green Party of Canada its highest marks in a recent evaluation of political parties' platforms.

The Conservatives fared the worst, with only four "very strong" rankings. They came in social/cooperative housing, affordable rental and homeownership, foreign ownership concerning housing, and economic development).

Stephen Harper's party had three "strong" rankings: transit/infrastructure/active transportation/transit safety, national housing strategy, and affordable housing/social housing).

The Conservatives were "weak" or "very weak" in the seven other categories.

The Liberals had 11 "very strong" and three "strong" rankings.

The NDP nine "very strong" and four "strong" rankings. The party was not rated on foreign ownership concerning housing because the Council for Canadian Urbanism couldn't find any data on its position.

According to the council, 81 percent of Canadians live in urban areas. The organization supports federal financing to make housing more affordable in cities.
