What you can bring

Whether in your checked luggage or carry-on, you’re permitted to carry up to 30g of recreational marijuana, with cannabis oil falling under general liquid restrictions (remember, you can only pack up to 100mL in your carry-on).

If you have a greater amount due to a medical marijuana prescription, you’ll need to have your documentation ready. Make sure that your medical marijuana documentation aligns with the guidelines of the Access to Cannabis for Medical Purposes Regulations so that you don’t run into any hassles during travel.
Watch your age

The legal age for marijuana usage varies across Canada, as it does for alcohol consumption. Before you fly across provinces and territories, check to be sure that you’re allowed to land in your destination with cannabis.

Not sure what the legal age is across the country? Keep an eye on Quebec: the government there has plans to increase the legal age limit for cannabis consumption from 18 to 21

Remember — don’t travel with more than the limits for recreational cannabis use, and don’t dip across Canadian borders with marijuana in your possession!

Stay updated on travel requirements and guidelines, pack appropriately, and give yourself a bit of extra time to get through airport security, just in case.

Then fly off to your next destination and spark a Lil something to celebrate.
