About Testing Labs
All cannabis products sold in Canada must pass laboratory testing authorized by Health Canada before reaching consumers. Canadian cannabis testing labs are accredited under ISO/IEC 17025 standards and conduct mandatory analysis for potency (THC/CBD), pesticides, heavy metals, microbials, residual solvents, and moisture content. Health Canada maintains a list of approved testing service providers, and all LP products must include Certificates of Analysis (COAs) available to regulators and consumers. Canada's nationally standardized testing framework ensures consistent consumer safety from coast to coast. Cannabis Promotions supports Canadian testing labs with branded promotional materials for industry conferences and business development.
