§Source summary
Canada Shipping Act 2001 — Pollution Prevention — Canada Shipping Act 2001 — Discharge Prohibitions
It is prohibited to discharge overboard any sewage, oily water, or plastic from a vessel in Canadian waters except as permitted. Vessels with holding tanks may need no-discharge labels at the overboard discharge valve to prevent accidental or deliberate prohibited discharge.
Read official source✓Plain English
If your boat has a marine toilet (head), the overboard discharge valve — if one exists — should be clearly marked so crew do not accidentally open it in a no-discharge zone. All Canadian inland and most coastal waters are no-discharge zones for sewage.
