No. The prospect of legal cannabis has prompted some dispensary owners to expand, despite remaining federally illegal. The only way to buy legal medical cannabis in Canada, is through the ACMPR. 

The Access to Cannabis for Medical Purposes (ACMPR) are the Government of Canada's regulations that enable patients to obtain authorization to access cannabis for medical purposes.

It's a mail order system that allows patients to sign up with a licensed producer, and legally purchase cannabis online in Canada.

Under the ACMPR, Doctors or Nurse Practitioners are responsible for authorizing patient access to medical cannabis.

Yes, as long as you are using a different medical document for each. You can’t apply to different LPs with the same medical document. You can split your prescribed daily prescription amount among different LPs with separate medical documents.

We can refer you to a Health Care Practitioner who will assess you for eligibility to medical cannabis. Send us an email, and we will send you more information.

Medical insurance plans generally do not cover the cost of medical cannabis in Canada. In some cases it can be claimed with Veterans Affairs or as a health deduction from personal income tax. Speak to your doctor or insurance provider for more details. 

Once an order is placed, all sales are final. If there is a mistake on an order placed, please contact us immediately and we will do our best to assist you.

Five gram increments allow us to pre-package our orders, which means shorter processing time, and faster delivery. We’ve found it works pretty well.

Your Healthcare Practitioner must include a daily limit on your Medical Document. You may order up to your month's worth of cannabis, each month.

For example, If your daily dosage is 2 grams/day, you can order up to 60 grams every 30 days.

You will receive an email with a tracking number when your order leaves our facility. The tracking number lets you track your shipment through the carrier’s website.

If you’re not happy with your product for whatever reason, let us know, and we’ll make it right.

Your cannabis needs to be stored in the jar we ship it to you in. This jar has all of your patient information, and is proof that you are legally allowed to possess medical cannabis within Canada.

We can point you in the right direction based on your preferences, and your previous experience with using cannabis. A good rule of thumb is to start low and go slow, and follow your nose.

Cannabinoids are the active compounds found within Cannabis. There are at least 100 different cannabinoids that we know about, with THC and CBD being the ones with the relatively highest concentration in the plant.

THC and CBD are both cannabinoids found in cannabis.

Indica and sativa are considered to be a species of the genus Cannabis. However, it’s relatively rare to find either a pure Sativa or a pure Indica strain, as most cultivated strains of cannabis today are a hybrid of the two, being either indica or sativa dominant.


As more scientists study this plant, we’re learning that the classification of cannabis into Indica, Sativa, and Hybrid is incredibly oversimplified, and the subject of intense debate. The cannabis plant contains a huge array of cannabinoids, terpenes, and flavonoids, all of which interact with your body’s biochemistry in a very unique way. This means that you may have a totally different reaction to one strain, then say, the next person.


We’ve found that a better way to classify cannabis is to go by the ratio of THC to CBD. That’s why you’ll see all of our strains in three different categories, THC dominant, CBD dominant, or a balanced ratio.

Terpenes are the fragrant compounds that gives cannabis it’s aromatic diversity. Found throughout the natural world, terpenes and can be found in many other plants, herbs and fruits. This is why certain strains will have the familiar notes of citrus, blueberry, pine, hops, etc.
