Cannabis Testing

High quality testing provided by one of Montreal’s leading cannabis testing companies

About Cannabis Testing

We provide Cannabis testing for all types of cannabinoids-based products including flowers, trims, pre-rolls, oil, vape, capsules, rosin, hash, kief, suppositories, topical cream, and edible products. Methods are validated as per the requirements of Health Canada, US Pharmacopoeia and European Pharmacopoeia.

Methods and Equipment

Our facility has been licensed since April 2018, and we have methods validated to analyze for cannabinoids, pesticides, terpenes, aflatoxins, Ochratoxin A, heavy metals, residual solvents, peroxide values, disintegration, water activity, pH, moisture content, loss on drying, foreign matter, content uniformity and weight variations. We also have validated USP and EP harmonized microbial testing methods using both traditional plating and qPCR technique.

Our Services

Cannabinoids Testing 

Validated HPLC-PDA methods for the quantitative determination of ten major cannabinoids, which have passed proficiency testing organized by Proficiency Testing Canada.


Our Cannabinoids testing methods are validated for the following cannabis products: 

  • Cannabis flower (including pre-rolls) 
  • Cannabis oil 
  • Cannabis concentrates (distillate, resin, rosin) 
  • Cannabis isolates 
  • Hash 
  • Kief 
  • Edible products (beverages, gummies, chocolates) 
  • Subligual strips
  • Suppository products 
  • Butter
  • Swab
  • Topical Cream
Microbial Analysis

Reliable validated USP and EP harmonized traditional plating method and qPCR method to test Total Aerobic Microbial Count (TAMC), Total Yeast and Mold Count (TYMC), Bile Tolerant Gram-Negative bacteria (BTGN), Escherichia coli, Salmonella Spp, Pseudomonas aeruginosa, and Staphylococcus aureus.

Heavy Metal Testing

Validated ICP-MS methods for the quantitative determination of Arsenic (LLOQ 0.10 ppm), Cadmium (LLOQ 0.10 ppm), Mercury (LLOQ 0.05 ppm) and Lead (LLOQ 0.25 ppm). The methods fulfil tolerance limit requirements from Health Canada, ICH Q3D, EP <5.20> and USP <232>.

Aflatoxins Testing

Validated HPLC/MS/MS method for the determination of Aflatoxin-B1, Aflatoxin-B2, Aflatoxin-G1 (LLOQ 0.05 ppb) and Aflatoxin-G2 (LLOQ 0.05 ppb), which fulfil the requirement of Health Canada, EP <2.8.18> and USP <561>.

Pesticides Testing

Validated LC-MS/MS and GC-MS/MS methods to determine 96 pesticides according to Health Canada Mandatory Cannabis Testing List.

Terpenes Analysis

Validated GC-MS/MS method to determine 39 major terpenes in cannabis samples. Each of the terpenes has been identified using a single standard to ensure the accuracy of results. Method limits of detection for each of the terpenes are 20 ppm or lower.

Residual Solvents Testing

Validated GC-MS/MS method to determine 26 residual solvents as per limits required by Health Canada for cannabis samples. 

Stability Testing

Two stability chambers which can provide storage conditions for cannabis product at 25°C/60%RH, and 40°C/75%RH, respectively. 

Ochratoxin A Testing

Validated LC-MS/MS method to determine Ochratoxin A in cannabis products with an LLOQ of 20 ppb which fulfils the requirement of USP <561> and EP <2.8.22>.

Peroxide Value Testing

Validated method using Karl Fischer titration technique.

Disintegration Testing

Validated method as per USP <2040> and EP <2.9.1> to determine whether capsule or tablet samples disintegrate in liquid medium.

Water Activity Testing

Validated method as per EP <2.9.39> to determine water activity.

Loss on Drying and Moisture Content Testing

Validated methods using both moisture analyzer and ovens to test loss on drying and moisture content.

Foreign Matter Inspection

Internal procedures to conduct foreign matter inspection for samples as per USP <561>.

pH Measurements

pH measurements as per procedures described in USP <791>.
