Clean Water Act, 2006, S.O. 2006, c. 22 — under the Clean Water Act, 2006

Plain-language summary · AI-assisted · not legal advice

Several amendments to Ontario's source protection planning rules that were previously listed as coming into force 'on a day to be named' now have confirmed dates. A set of changes affecting how source protection plans are amended, published, and made publicly available — including new deemed-approval timelines, a Director sign-off requirement before submitting plan amendments to the Minister, and expanded public posting duties — will take effect mid-2026. A separate set of changes replacing how prescribed instruments must conform with source protection plan policies, and adding new ministerial regulation-making powers, will take effect at the start of 2027. One pending amendment to the Minister's review options for source protection plans has also now come into force. Source protection authorities, municipal planning bodies, and instrument-issuing bodies should review these timelines to confirm their obligations and update internal processes accordingly.

Who this affects: source protection authorities · source protection committees · municipal councils and planning authorities · bodies that issue or amend prescribed instruments · the Minister of the Environment
