The terms you're referring to, “mild” and “light”, through an agreement with the Competition Bureau that Mr. Cunningham mentioned just a moment ago, have not been placed on tobacco products in Canada for the last four or five years, so this regulation is merely putting into law what is currently the standard practice in the tobacco industry in Canada today.
I would go on to say, however, that those terms do still appear on a number of contraband products that continue to flow off the first nation reserves and are sold throughout the country today, but in terms of the legal tobacco market, they're not used on tobacco products today.
