With respect to package warnings, Canada will be in a position of world leadership. Canada will not have the biggest warnings in the world. Australia is soon to have about 82.5%, with 75% on the front and 90% on the back; Uruguay already has 80%; there are some other countries, such as tiny Mauritius, which has 65% on average on the front and back.
These regulations are outstanding and will put Canada in a position of world leadership. One thing to note is that Canada will be the only country to have warning requirements and message requirements inside the package. Taken as a whole, that must be assessed in terms of the quality of the Canadian regulations.
