There are doubts that high-strength beers are causing as much harm as critics say.  

The products are sold as singles in supermarkets and liquor stores and are stronger than RTDs, ranging from seven to 16 percent.  

'Communities Against Alcohol Harm' has been raising the issue at a number of public hearings - calling for a ban.  

But Brewers Association Executive Director Dylan Firth says a blanket ban would be an overreach.  

He says, if there are specific problems, they can be imposed on the licenses of each product.
