As of June 1st, all bars will be smoke-free. This City of Toronto webpage from Toronto Public Health: Smoke-free lifestyle includes background information, the By-law, signs, and a poster.
I was very excited to see this advertised in the newspaper on the weekend. A few weeks ago I was out with friends in a smokey bar. My lungs were sore for several days afterward, and I then came down with the horrible cold that has been going around. Recovery from my evening out, then, was several weeks. I vowed not to go into another smokey place again.
So, I am just thrilled. First order of business on June 1st will be to go out and celebrate! Of course, I will check first whether the owners plan to comply with the new By-law.
