May 16 - The Toronto Star and U.S.-based news site Gawker report that Mayor Rob Ford was seen on video smoking what appears to be crack cocaine and making racist and homophobic comments. They also say the video is being shopped around by a group of men allegedly involved in the drug trade.

___

May 17 - Ford calls the allegations "ridiculous" and accuses the Toronto Star of "going after" him. Ford's lawyer Dennis Morris calls the reports "false and defamatory" and says it's impossible to tell what a person is smoking by watching the video.

___

May 26 - On his weekly radio show on Newstalk 1010, Ford says he's "moving forward" from the allegations and plans to run for re-election. He attacks the media for their coverage of the growing scandal, calling them ``a bunch of maggots.''

___

May 30 - The Toronto Star alleges Ford told senior aides not to worry about the alleged video because he knew where it was. The mayor refuses to comment, but says he won't step down.

___

Nov. 3: Ford apologizes on his weekly radio show on Newstalk 1010 for making mistakes including appearing in public while "hammered" and texting while driving. But he tells AM640 the next day: "I'm not an alcoholic, I'm not a drug addict."

___

Nov. 5: Ford admits he smoked crack cocaine about a year earlier while in one of his "drunken stupors." Despite the admission after months of denials on the drug use question, he insists he had been truthful. "I wasn't lying," he told reporters. "You didn't ask the correct questions. No, I'm not an addict and no I do not do drugs." Ford says he has nothing left to hide.

___

Nov. 7: A video is posted online by the Toronto Star and Toronto Sun that shows Ford spewing obscenities and using threatening words, including "kill" and "murder." The mayor tells reporters moments after the video is posted that he was "extremely" drunk and is "extremely" embarrassed.

He later apologizes and says he is getting professional support. City councillors call on him to resign. Ford refuses.

___

Nov. 18: City council votes by a wide margin to slash Ford's mayoral budget and hand many of his duties to the deputy mayor. Ford calls it a "coup d'etat" and vows it will be war in the October 2014 municipal election.

Dec. 9: In a televised interview with Conrad Black, Ford claims that Toronto Star reporter Daniel Dale was in his backyard in May 2012, "taking pictures of little kids." He says "I don't want to say that word but you start thinking what this guy is all about." Dale later serves Ford with a libel notice, alleging Ford insinuated he is a pedophile. He later announces he is not proceeding with the lawsuit after Ford apologizes and retracts his comments, though only after a first attempt at an apology that Dale found unsatisfactory.
