Toronto Mayor Rob Ford will be back at City Hall Tuesday morning for a special meeting on a proposed downtown casino, but is expected to face questions from the media and some councillors about allegations that he was recorded on video allegedly smoking crack cocaine.

Ford and his brother, Coun. Doug Ford, abruptly cancelled their weekly radio show Sunday after news broke about the video on U.S. gossip website Gawker, and then in the Toronto Star. The video’s authenticity has not been established, and Ford has called the allegations “ridiculous.”

Ford remained out of sight over the Victoria Day long weekend. However, council returns to work on Tuesday for a special meeting about the casino proposal, which was put back on the agenda after a majority of councillors signed their names to a petition asking that the debate go ahead.

Last week, the mayor announced a decision to delay the debate until June 11. However, under city council rules, special meetings can be called with 48 hours’ notice if it has the support of at least 23 councillors.

On Monday, Deputy Mayor Doug Holyday said he expects Ford to answer reporters’ questions about the alleged video early this week. Holyday said it’s possible that some councillors will raise the alleged video at Tuesday’s meeting.

“Some members of council might try to put this on the floor of council to embarrass him,” Holyday told CP24 Monday afternoon.

“But I don’t imagine the speaker will let that stand in order. And I don’t think it is in order. There isn’t an item on the agenda to deal with this subject. And we’re there to deal with casinos, and that’s what we’ll deal with.”

Holyday said he “was stunned” when he first heard about the allegations against Ford, and said he has “never even seen him take a drink.”

But he said the mayor is “going to have to give some explanation,” because the issue is “not going to go away.”

“And if the video doesn’t come out then I don’t know where we stand because it’s almost like someone repeating a story that someone else told them,” Holyday said. “And that’s about what it is in this case. Now it’s a video, which might be a little stronger than a statement, but it still isn’t proof positive and the video itself would have to be examined.”

Since news of Friday’s story broke, Gawker has launched a crowdsourcing campaign to raise the $200,000 needed to purchase the video.

Approximately $81,000 was raised through donations on the website Indiegogo by Sunday at 9 pm. ET.

Last week, Ford took a firm stance on the proposed casino, saying that without a guarantee of at least $100 million a year in revenue for the city, the deal is “dead.” He lashed out at Ontario Premier Kathleen Wynne for her failure to come up with a funding formula detailing what the city’s cut will be for hosting a casino.

Hours later, Finance Minister Charles Sousa confirmed that the Ontario Lottery and Gaming Corp. had given him a revised funding formula for cities that host gaming facilities. Under the new agreement, the city will get approximately $53.7 million a year.

That hosting revenue includes Toronto’s cut from a downtown casino, as well as the slots at the Woodbine Racetrack.

The letter requesting the special meeting was delivered to the city clerk’s office on Sunday. The meeting is scheduled to take place on Tuesday at 9:30 a.m.
