You're right. They're examples of cigarettes I've personally purchased on various territories: Tyendinaga, near Belleville; Kahnawake, near Montreal; or on the American side of Akwesasne.
The products sold in Canada do not have the picture-based health warnings required by law in Canada. They do not comply with the ignition propensity standard for fire safety and flammability, pursuant to Mr. McKay's bill, and they are very cheap, perhaps $6 for a carton of 200 cigarettes, compared with the legal price of $50 to $70. It's a massive problem.
They're extremely easy to acquire. Non-natives are abusing the exemption by going on reserve, and the products intended for the reserve are being diverted off reserve. It's very easy; people can have them delivered to their workplace or to their home.
