Ottawa also instituted a smoking ban almost a decade ago. Some bar owners initially claimed it would drive them out of business. However, in the years following the smoking ban the number of bankruptcies for bars/restaurants actually went down, and in many cases, when one bar closes, another one opens in the exact same spot. Employment is also up in the field.
That said, I am curious about one thing... the number of people who smoke is a minority, and has been for some time. You would think that more bars/restaurants would be eager to institute non-smoking policies to cater to the majority, yet prior to the ban I can only think of one restaurant (out of hundreds or thousands in the city) that were specificially no smoking. Anyone have any thoughts about why that is? Do smokers, even though they are in the minority, have more influence in getting friends to go to pro-smoking places than their numbers suggest? Or were bar owners unwilling to risk making changes that might help business, or might harm it?
