Cannabis Health & Safety
How do I report an adverse reaction?
If you purchased a product from an Authorized Cannabis Store and you’ve experienced an adverse reaction, reach out to the retailer to initiate a return or exchange. The store will then open an investigation with the OCS regarding the product.
If you purchased a product directly from OCS.ca and you’ve experienced an adverse reaction, please contact us at 1-888-910-0627, between 9 a.m. and 5 p.m. ET, from Monday to Saturday. One of our customer service representatives will be able to assist you further.
You may also choose to report an adverse reaction directly to Health Canada.
