Toronto Mayor Rob Ford will return to work on July 1, about two months after he took a leave of absence to seek professional help for substance abuse.

The mayor will leave the GreeneStone rehab facility in Bala, Ont. on June 30, Coun. Doug Ford told CP24. The next day, Rob Ford plans to launch his political comeback.

The mayor plans to continue campaigning, starting with public events held in Toronto on July 1, despite calls for resignation over allegations of drug and alcohol use.

"Can't wait to have him back and get into the race," his brother Doug Ford told reporters last week. "Game on."

On April 30, Ford announced he was taking an immediate leave of absence after a new video emerged that allegedly showed the mayor smoking from a pipe. The video has not been viewed by CTV News.

On the same day, an audio recording of a man who sounds like Ford surfaced. The man could be heard making inappropriate comments about fellow mayoral candidate Karen Stintz.

During his time in rehab, mayor has been making and receiving phone calls and has also been spotted off the addictions centre campus.

Recently, he celebrated his birthday at a Bracebridge, Ont. restaurant and bar on May 28, and servers said he was not served any alcohol. He was also spotted outside a shopping plaza in the town on May 16.

Last month, his SUV was impounded when a female driver was charged with impaired driving in Bracebridge. Lee Anne McRobb, who was the lone occupant of the vehicle, reportedly met Ford in rehab.
