Cant of course speak for Ontario as I'm in the UK. But here its a class C 'drug' (class A being the 'worst'). If they apply the same logic then an age limit doesnt apply as its a prohibited substance whatever age. Stry, giving a child of 5 alcohol in the home is not illegal here though I certainly didnt give it to my kids. Have you got anything like the Citizens Advice Bureau you could ask? Or maybe a solicitor?
