TORONTO - Ontario's political parties are lining up their candidates for a still uncalled Toronto byelection to replace former deputy premier George Smitherman.

The New Democratic candidate will be Cathy Crowe, a nurse and affordable housing activist who lives and works in the Toronto Centre riding.

Crowe is the author of "Dying for a Home," and was the subject of the 2002 documentary "Street Nurse."

Former Winnipeg mayor Glen Murray is expected to win the Liberal nomination for the Toronto Centre byelection on Wednesday.

Murray has the support of some key Liberals, including Smitherman, who officially resigned as a member of the legislature last weekend to clear the way for his bid to become mayor of Toronto.

The Progressive Conservatives plan to nominate their candidate for the Toronto Centre byelection later this month.

Premier Dalton McGuinty is expected to call the byelection shortly, although he can wait six months before he must schedule the vote.
