Toronto's mayoral race is expected to heat up on Monday.
Karen Stintz plans to kick off her campaign at 10 am. The city councillor tweeted Friday that she had filled out her paperwork to challenge Rob Ford for the mayor's office.
Stintz first announced her intention to run on "a fiscal agenda" in October. She pledges to base her campaign on "making sure that Toronto remains an affordable place to live, making sure that we build the transit plans that have been approved, looking to figure out how to improve transit in the city, safe neighbourhoods, and making sure that as we develop our city, that we are protecting the neighbourhoods that have already been established."
Stintz identified building a new subway line to take pressure of existing routes through the core as a campaign priority.
In 2010, Rob Ford picked Stintz to Chair the TTC, a post she formally gave up over the weekend in order to run for mayor.
Once a member of Ford's inner circle, Stintz has butted heads with the mayor over transit planning in recent months. Last summer, councillor Doug Ford said her appointment to the TTC was "the biggest mistake we ever did".
Stintz will join over two dozen, mostly unknown declared mayoral challengers. Newstalk 1010 host John Tory and Miller-era budget chief David Soknacki are in the running. Trinity Spadina NDP MP Olivia Chow is expected to join the race this spring.
Toronto votes October 27th.
