At Bloom Labs, we perform the mandated testing required for compliance under Health Canada’s Cannabis Act for both dried flowers and oils. Tests can be purchased as a compliance package or individually. Our services are tailored to fit your needs. 

To meet the Cannabis Act requirements, your product will need to undergo the following: cannabinoid profiling and potency, aflatoxins testing, microbiological analysis, heavy metal detection, pesticide screening, moisture determination as well as foreign matter inspection. Cannabis oils will also require testing for residual solvents. In addition, we offer a variety of luxury services, including a terpene profile, an elemental analysis of 31 elements and confirmation of oil density.

Cannabinoid Profiling and Potency

The potency of cannabis is measured through profiling cannabinoids. The cannabinoids many consumers are interested in are tetrahydrocannabinol (THC) or cannabidiol (CBD). However, there are seven other major and minor molecules that could be present. Cannabinoids are what give cannabis its psychoactive and medical properties. Testing for potency is essential and required so that you can be aware of the cannabinoid concentrations in your product. We use high-performance liquid chromatography (HPLC) with a diode array detector (DAD) to measure cannabinoids.


It’s important to be certain that there are no harmful toxins or chemicals growing in your cannabis. Aflatoxins are a group of mycotoxins produced by different types of moulds. They are extremely toxic to humans and are considered to have poisonous and carcinogenic properties. Testing for Aflatoxins in cannabis is a requirement under the Cannabis Act.

Microbiological Analysis

Microbes are types of bacteria, yeasts and moulds that are often not visible to the naked eye. The presence of microbes can be common for cannabis, particularly for cannabis that is grown inside. In some cases, microbes are beneficial to human health. However, some types can cause damage to the plant or be harmful to humans. At BloomLabs, we use European Pharmacopeia (EP) compliant testing methods to discover any traces of salmonella, escherichia coli or bile-tolerant gram-negative bacteria. We will also perform a total aerobic microbial count, and total combined yeast and moulds count.

Moisture Determination and Water Activity

Providing a water analysis of your cannabis sample will ensure that the consumer has an optimal experience. The ideal moisture content of cannabis should be between 10% to 14%. When the moisture is greater than 14%, it may promote mould formation that can flag your product for failure according to Health Canada’s standards.

Heavy Metal Analysis

Lead (Pb), cadmium (Cd), mercury (Hg) and arsenic (As) are often referred to as heavy metals due to their high mass and high-density properties. These heavy metals are typically found in the majority of soils. During the growing process, plants can uptake these containments. We have a state of the art inductively coupled plasma mass spectrometer which allows us to analyze these metals at low levels. We also offer the option to perform an additional 31 elemental analysis to ensure your product is free and clear of any unwanted elements. This analysis can provide information on other elements in your cannabis plant, which might be related to uptake and overall plant health.

Pesticide Screening

Canada’s cannabis regulations state that licensed producers are not allowed to use unauthorized pest control products in the cultivation or production of cannabis. The Pest Management Regulatory Agency (PMRA) currently lists 22 registered products that are approved for use with cannabis. If an unregistered product is used on cannabis, it may cause serious harm to the consumer. Our pesticide screening will detect all 96 PMRA banned pesticides for cannabis and confirm that your product is safe for use. For a full list of banned and approved products, please visit Health Canada. 

Foreign Material Inspection

A foreign matter inspection is a physical and visual examination of the product. This analysis will confirm the presence of unwanted materials or damaged product.


Terpenes are naturally occurring compounds that give cannabis its unique flavour and scent. While analyzing for terpenes is not required by Health Canada, a terpene breakdown can provide insight into your product for marketing purposes. It can also be beneficial to list a terpene profile on your product to help clients find the right strain to meet their needs. Our tests can identify over 30 terpene compounds. We use gas chromatography coupled with a mass spectrometer to complete our terpene testing.

Residual Solvents

In some cases, cannabis oils are extracted with solvents. There are three classifications of solvents based on their level of risk to humans. Coming in contact with solvents can lead to significant health issues, including headaches, nausea and more. Due to these potential risks, Health Canada limits the type and amount of residual solvents that can remain in cannabis oil, and therefore, testing is a requirement under the Cannabis Act.

Oil Density

Performing an oil density test can help define your oil cannabinoid concentrations in either an amount per gram of oil or per millilitre of oil.  At BloomLabs, we offer an oil density analysis as an additional option.
