Ontario pub owners are outraged over a new law to ban smoking in workplaces, enclosed public areas, and even patios by 31 May 2006. Canada's strongest anti-smoking legislation would eliminate separately-ventilated designated smoking rooms (DSRs) which more than 700 Ontario bars and restaurants have built at a cost of between C$15,000 and C$300,000.

Ontario's Restaurant Hotel & Motel Association stated that bar operators are already reeling from four consecutive years of falling revenues, and "still have a high proportion of customers who smoke. Asking these operations to go cold turkey will have a devastating impact on these small businesses."

Sales at liquor-licensed establishments in New Brunswick plummeted immediately following a similar smoking ban in October.
