Ontario will restrict the sale of vape flavours and high nicotine e-cigarettes in a bid to address youth vaping, Health Minister Christine Elliott announced Friday. The government also plans to expand prevention efforts and bolster services to help people quit vaping. Elliott cited recent studies that show youth vaping in Canada has increased 74 per cent in just one year, and that nearly one in five Grade 12 students report using an e-cigarette in the previous year. Elliott is also calling on the federal government to create a national tax on vaping products.
