Blending sustainability with science to produce pure, effective medical cannabis

Who We Are

You only get one life on this planet. Which is why good health is so important, but as someone that has to deal with a medical condition, you know that feeling healthy can be a challenge.
Congratulations for exploring an alternative form of treatment! Based in Hamilton, Ontario, Green Relief is a licensed producer under Health Canada’s Access to Cannabis for Medical Purposes Regulations (ACMPR). Our mission is simple: help our patients improve their quality of life. We also envision furthering the science of medical cannabis through research and using cannabis to advance sustainable agriculture around the world.

What Matters to Us


Our planet’s natural resources are depleting at an alarming rate, which is why it’s vital to reduce any harmful effects on the environment as much as possible. From how we grow our cannabis to low impact solutions at our facility, we implement sustainable measures across every part of our company.

Social Responsibility

Giving back to our community is incredibly important to us, and the unique way we grow cannabis enables us to do so on a large scale.

In addition to providing local shelters with healthy, organic fish and vegetables to feed those in need, we’re also exploring ways to integrate job positions for the physically disabled through the Ontario Disability Employment Network.


Our sales will enable us to invest in R&D to provide medical professionals with studies and papers they need to become more aware about the benefits of medical cannabis.

Our Phase II building will have a state-of-the-art, 10,000 sq. ft. laboratory designed to work with doctors and local universities to advance the science of medical marijuana.

Growing Cannabis With Fish

Yep, you read that right.
We’re the only medical cannabis provider in the world that’s producing by way of aquaponics, considered the most innovative and sustainable form of agriculture.
Aquaponics combines the best attributes of aquaculture and hydroponics, without the need to discard water or add chemical fertilizers. It produces 10 times the crop yield per acre and uses 90% less water than conventional farming.
So what does that mean for you? It means you’ll get a product that’s even healthier than organic, in its most natural form possible.

Committed to Our Product


To ensure the health and safety of our cannabis, we implement strict testing protocols so that what you buy is free of mold, pesticides, bacteria, chemicals, microbials and other harmful materials.


Medical cannabis is exactly that: medicine. As such, it needs to be as consistent as possible from batch to batch in order to produce replicable results for patients.

We grow from the tissues of only the best plants and use them as stock every time. Plus, our on-site laboratory allows us to constantly be improving even our best clones.


We harvest every two weeks, which means maximum freshness for you. Our product will never sit packaged in a vault for months waiting to be sold. Plus, our experienced quality assurance team reviews everything before it leaves our facility.
