Rob Ford has dared Toronto Police Chief Bill Blair to arrest him.

The controversial Toronto mayor became heated in a press scrum on Thursday when asked if he owes Blair an apology over profane comments he made about the chief in the now infamous Steak Queen video.

Ford said he won't be apologizing to Blair and essentially told the chief to put up or shut up when it comes to the police investigation on him.

"I want to see how much money he's spent on following me around and if he's going to arrest me, arrest me," Ford said. "I have done nothing wrong and he's wasted millions of dollars. I want him to come clean and say how much did it cost the taxpayers for surveillance on me and the planes that he had to rent. That's absolutely game-playing, that's politics and I am not apologizing."

Ford was also unfazed by Blair's remarks to journalists this week that he was "disgusted" by Ford's profane rant several weeks ago. The mayor was recorded calling the chief a "c**ksucker" and ranting in Jamaican patois.

"He's embarrassed? How about him embarrassing my family, my kids, my community, my friends, following me around for five months, spending millions of dollars with using taxpayer money," Ford said. "If there's anyone who owes an apology, he owes an apology to the taxpayers."

The mayor said Blair should come clean on how much money police have spent on surveillance only to come up with "nothing."

"Coming up with me urinating in a parking lot? Coming up with an empty vodka bottle? Come on," he said.

When asked by a reporter if his behaviour is becoming of a mayor, Ford said he already addressed those concerns.

"I think you've seen a physical change in me," he said.
