Role of Health Canada in Hemp

THC Sampling and Analysis

As part of the license requirements for growing hemp, producers must provide proof that their hemp crop has a THC level of less than 0.3 %.

A list of varieties is updated each year that are exempt from annual THC testing.  Each year Health Canada reviews the THC test results that have been submitted.  Although producers may have sampled a field, samples may also still be taken by designated inspectors for routine variety monitoring.

It is mandatory that all new varieties that are not on the THC testing exempt list, known as the List of Approved Cultivars (LOAC), be tested. It is the producer’s responsibility to hire a person approved or licensed by Health Canada as a hemp sampler.  Producers must check with their contractor (the company to which they have contracted their hemp production) or the Health Canada website for a list of authorized samplers.

The sampler must follow the Health Canada guidelines outlined in “Guidance on Sampling and Analysis of THC (Delta-9 Tetrahydrocannabinol) in Hemp.”  This guideline includes information on collecting, drying, and submitting hemp samples to an approved laboratory for analysis.

The laboratory analysis determines the level of THC found in the crop sample and provides a report to the producer. A copy of the report must be submitted to Health Canada to be in compliance with the cultivation license. The producer must pay for both the sampling and laboratory analysis.
