Vaping / E-cigs — Canada

You can bring your own vape, but declare it: the visitor limit is 12 containers or fewer holding at most 120 ml of liquid (or 120 g solid), and you must be 18. Only one unit comes in free of Canada's vaping excise duty, and US-bought e-liquid carries no Canadian excise stamp, so expect to be assessed. Canada's 20 mg/ml nicotine cap and its flavour bans are rules about what shops may SELL - no Canadian law read here makes it an offence to possess your own device.
