Yes. The principal Canadian reference is the Canadian Council of Ministers of the Environment (CCME) Guidelines for the Management of Biomedical Waste in Canada (1992), developed jointly with Health Canada, which defines the biomedical-waste categories (human anatomical, animal, microbiology/biotechnology laboratory, blood and body-fluid waste, and sharps) and recommends handling, storage, treatment and disposal practices. The CCME document is a national guideline rather than binding federal law — it is implemented and enforced province-by-province through provincial health-care-waste regulations and, on the handling/storage side, through CSA standard Z317.10, Handling of Waste Materials in Health Care Facilities and Veterinary Health Care Facilities, which most provincial regulators reference directly as the enforceable technical standard.
A candidate answering this question should name both documents specifically rather than a generic "yes, there are guidelines" — the CCME guideline sets the categorical framework (what counts as biomedical waste and in which class), while CSA Z317.10 is what an inspector or accreditation auditor actually checks a facility against, so both together, not either alone, describe the real Canadian regulatory picture. This two-tier pattern (national policy guideline plus a CSA technical handling standard) recurs across several areas of Canadian environmental and occupational practice, and is worth recognizing as a general structure rather than a fact specific only to biomedical waste. A candidate who names only one tier has given a partial, not a wrong, answer. In practice, an engineer working with a health-care client would consult both documents together: the CCME guideline to understand the categorical framework, and CSA Z317.10 to design the actual handling, storage and transport procedures the facility will be audited against.
