I would have to check, but I think so.
For us, sugary drinks are water with sugar added. After that, you are getting into the juice category, which is perhaps the product you are talking about. That is why the label says “no added sugar”.
Currently, the problem with juices is that they are not good for one's health when they are consumed in large quantities, because the sugar they contain gets into the system quickly. Up until now, the Canada Food Guide has seen one juice as one serving of fruit. Science has shown that this is false, because juice has lost all its fibre, which serves to slow digestion.
That is about to change, but, at the moment, Canadians are not aware of it. A lot of awareness still needs to be done in terms of juices. For us, the tax is limited to water with added sugar, though it may eventually apply to juices.
We have to think about disadvantaged communities, for example, that really believe that they will get the vitamins they need from drinking juice. They are not able to get healthy fruits and vegetables. Before taxing juice, we have to raise awareness.
Diet drinks—this is somewhat related to your question—do not contain sugar; they contain sweeteners. They are just as harmful for the teeth as normal sugary drinks, because they are just as acidic. The science on this is not clear, and more research on the subject is needed. Our diet contains a lot of sweeteners and we do not know whether, in the long term, quantities like that can be harmful to the health. As a result, we just have to be careful for the moment.
