The omnibus bill would treat e-cigarettes just like tobacco cigarettes, with a total ban on sales to youth and on using them in restaurants and public buildings.
"Until we have the evidence as to how bad or what the evidence is on electronic cigarettes, all we're saying is let's not get our kids started on this," said Associate Health Minister Dipika Damerla. "The evidence shows if young kids see people smoking or vaping, they are likely to take up smoking or vaping."
Even though e-cigarettes do not produce second-hand smoke, they still send the wrong message to teens, added Damerla.
"We're not banning it," she said. "All we're saying is we want to regulate it and there's absolutely nothing in this legislation that would stop an adult from using it."
The New Democrats said the Liberals should have taken action sooner.
"Every month that goes by, more and more youth pick up smoking by experimenting with e-cigarettes and then making the switch," said NDP health critic France Gelinas.
Damerla said the restaurant and motel industries asked for regulations on e-cigarettes so they don't have to argue with customers who aren't clear on the rules, and noted about 43 American states and the province of Nova Scotia have already regulated e-cigarettes in some way.
The Ontario bill, which brings together three previous pieces of legislation, would also ban all flavoured tobacco products, many of which are designed and packaged to appeal to teens, and will expand the previously planned prohibition to include menthol cigarettes.
"We know that flavoured (tobacco) and menthol cigarettes are aimed squarely at children and are meant to addict children and teenagers," said Dr. Scott Wooder of Stoney Creek, a former president of the Ontario Medical Association.
"It's easier for them to get started on menthol cigarettes," added Wooder. "It soothes the bitter burned tobacco taste of cigarettes."
The Canadian Cancer Society called the ban on flavoured tobacco "a giant step forward in protecting the health of Ontario youth and preventing cancer," and applauded the "bold decision" to include menthol cigarettes in the ban.
The industry will have up to two years to phase out menthol cigarettes, but most other provisions of the bill will kick in by Jan. 1, 2016, said Damerla.
The National Coalition Against Contraband Tobacco and the Ontario Korean Businessmen's Association, which says it represents the majority of independent convenience store retailers, said banning menthol will only drive more smokers to cheap, illegal cigarettes.
"The ban of yet another long-standing legal product will only lead to increased profits for illegal traffickers, and harder times for law abiding family businesses," said Don Cha of the Korean Businessmen's Association.
The Progressive Conservative said the Liberals were good at banning things but should take more concrete steps to lower smoking rates.
"We should be banning illegal smoke shacks that are really a way for kids to get very, very cheap cigarettes," said PC critic Bill Walker.
The bill will also require restaurants and grocery stores with more than 20 outlets in Ontario to list calorie counts on their menus and menu boards.
Mandating calorie postings on menus "will require complex regulations that will take time and industry collaboration to be successful," warned Restaurants Canada, which represents 30,000 restaurants, bars, caterers and suppliers.
"Calorie counts can only be provided when there is a high degree of standardization," said Restaurants Canada spokesman James Rilett. "While this is common in food manufacturing, it's the exception in a restaurant setting."
The NDP said the Liberals should have also mandated sodium levels be posted alongside the calorie counts on restaurant menus.
"It is something that's done in more and more jurisdictions and it's something that's easy to do," said Gelinas. "It's a flag that you put on the menu."
