Toronto's police chief has filed a defamation notice against Mayor Rob Ford's brother for comments the city councillor made earlier this month.
Doug Ford suggested two weeks ago that Chief Bill Blair helped leak information that police were preparing to subpoena the mayor in an ongoing investigation as "payback."
At the time, Blair said Ford was lying and warned that he was prepared to take legal action.
Toronto police spokesman Mark Pugash said the defamation notice was handed to the councillor on Monday night.
"What the notice specifies is a public retraction and apology in a forum to be agreed (upon) beforehand by Chief Blair," he said. "There's no mention of money at all in the document."
Pugash added that the legal action is being pursued by Blair personally, and doesn't involve taxpayer money.
"The next step is with the councillor," Pugash said.
Doug Ford said Tuesday that the issue was with his lawyers and refused to directly answer questions about whether he would apologize to Blair.
"There is no lawsuit as far as I know," he said.
Ford also criticized Pugash's role as a spokesperson for Blair's "private issues."
Meanwhile, Rob Ford didn't answer reporters' questions about the defamation notice at city hall on Tuesday.
On Aug. 1, the Toronto Star cited sources saying police were preparing to subpoena the mayor to testify at a preliminary hearing for his friend Alessandro (Sandro) Lisi, who is facing drug and extortion charges.
Doug Ford blamed the apparent leak on Blair, calling it politically motivated.
"When you tell the media there's a subpoena and don't tell anyone else? That alone says it all right there. That says it all," he said at the time."It's disappointing that the police chief, in my opinion, would condone this behaviour from his own department.''
Toronto's police services board had announced earlier that week that Blair's contract would not be renewed, effectively terminating his position as of next April.
Mayor Rob Ford has publicly criticized Blair ever since a police investigation last year turned up a video which appeared to show the mayor smoking crack cocaine.
At a news conference last October, Blair had said he was disappointed at what the video showed.
The mayor, who later admitted to smoking crack cocaine in a "drunken stupor,'' has publicly accused Blair of wasting taxpayers' money with the investigation and challenged the chief to arrest and charge him.
