Rob Ford's return: What will Toronto's mayor say today?

For once, it's not what Mayor Rob Ford has said that is causing a stir — the buzz surrounding his return to Toronto City Hall today following a stint in rehab is what he plans to say when he addresses media, something that remains a mystery.

Coun. Doug Ford says the public will have to wait and see what his brother plans to say Monday.

"Stay tuned, tomorrow at 3:30 [p.m.], the mayor will be addressing the people and I'm sure he'll be able to answer those questions," the councillor told reporters Sunday.

Doug Ford said the mayor is "looking forward to coming back, that's for sure."

Ford will make a statement to the media Monday, an event CBC.ca will stream LIVE n this story.

The mayor has been in rehab for about two months. He released a statement at the end of April acknowledging "a problem with alcohol," which led him to seek professional help.

Ford has already been spotted north of Toronto in a Barrie, Ont., clothing store, where he posed for some pictures that were posted on Instagram.

A spokeswoman for the shop said Ford was in the store on Saturday afternoon, but gave no other details.

"He looks the same, but a little lighter," his brother said. "He'll be hungry and looking forward to meeting the people."

Doug Ford said the people of Toronto can expect to see a completely new mayor.

His trip to rehab came months after he admitted to having smoked crack cocaine, likely during one of what he described as his "drunken stupors."

The mayor's crack use admission, as well as the events that followed, became part of an ongoing news story that was picked up around the world.

Ford, who turned 45 last month, is seeking a second term this fall. He is up against dozens of candidates who have registered for the mayoral race.

The news conference is by invitation only, something that has left many members of the city hall press gallery unhappy.

Rob Ford's communications director, Amin Massoud, told the Toronto Star that space restrictions are the reason not all press gallery members were invited.

The news conference will be held in the mayor's protocol office, a narrow room that can hold less than 30 people. Some reporters asked why it won't held in the members' lounge, which could comfortably accommodate all city hall reporters.

Massoud has said a feed of the news conference will be made available to reporters who weren't invited.

Torontoist editor Hamutal Dotan spoke about the media access issue on CBC Radio's Metro Morning show Monday.

"Members of the press gallery have not been invited," she said. "The president of the press gallery has not been invited. It's a very constrained group of people.

"If that's how [Ford] is handling himself on his first day back, that sets a very different tone than, for instance, if he held an open press conference where any member of the media could attend and we could ask questions on behalf of the residents of the city who want to know what rehab was like for Ford, how he's feeling now, how he plans to deal with the stresses of the campaign trail."
