The EDQA requires samples of environmental media collected in consequence of an order, permit, licence, approval or certificate issued under the Environmental Management Act to be chemically analyzed by a “qualified laboratory”. Under the Regulation a qualified laboratory means a laboratory registered with the former Canadian Association for Environmental Analytical Laboratories (now the Canadian Association for Laboratory Accreditation – CALA) as participating in the Association’s Inter-laboratory Comparison Program. CALA maintains a Directory of Accredited Laboratories which based on the Associations’ Inter-laboratory Comparison Program’s proficiency testing, are competent to perform specified chemical analyses. The EDQA Directory is essentially a subset of the larger CALA Directory, comprised primarily of CALA accredited laboratories located in British Columbia and Alberta.
