By a unanimous vote, Toronto's Board of Health solidified its opposition to a new casino.

On Monday, it adopted a report from Dr. David McKeown, Toronto's Chief Medical Officer of Health, that argues the potential costs outweigh the projected benefits.

McKeown's study points to poor air quality caused by increased traffic congestion, and 'negative family impacts' associated with problem gambling, like spousal abuse and divorce.

The Canadian Gaming Association calls the report flawed because it does not consider that gambling has been offered at Woobine for well over a decade.

Ontario's Lottery & Gaming Corporation wants to build a casino in the GTA and Toronto is their top choice for a building site.

City council makes the final decision on the casino question in April.
