Two mayoral candidates are attacking mayor Rob Ford on the day of his return to city hall.
Ford is back at work after spending two months in a Muskoka-area rehab centre.
In a statement, he apologized for his mistakes and says he is "resolved" to stay in the mayoral race.
One of his opponents in the mayoral race, John Tory, reacted to the statement outside city hall.
"I wish him well... in the continuing challenge of recovering from his personal difficulties," Tory said. "But my view also remains the same that he should resign from office."
Olivia Chow also spoke to reporters after Ford's statement.
"The question is not whether Rob Ford is clean and sober," Chow said. "The issue is that he is a failed mayor."
Karen Stintz released a statement, saying the city is "not defined by one person."
"Rob Ford is not Toronto and the upcoming election is not a referendum on Rob Ford," Stintz says in the statement. "Here's what the election is about: the kind of Toronto we want to live in and the kind of Toronto we want to build for our children."
Earlier, Chow has posted an ad to her YouTube page, attacking Ford's billion-dollar claim. Watch it here:
