TORONTO - One of Ontario's top labour leaders says he will back Hamilton New Democrat Andrea Horwath in the party's upcoming leadership contest.

CUPE Ontario president Sid Ryan says Horwath will be the leader `the Ontario NDP needs going into the next provincial election.'

Ryan says he's impressed with Horwath's knowledge and understanding and the `hope she represents for working people.'

CUPE is the largest union in Ontario with more than 200,000 members.

Horwath is one of four candidates in the running to replace Howard Hampton as party leader, a post he had held since 1996.

Horwath's rivals at the March 6 convention in Hamilton include Peter Tabuns, Michael Prue and party veteran Gilles Bisson.
