Ontario updates public lands work permit rules: new definitions, registration system, artifact/remains duties, and geotechnical exemption

ACTIVITIES ON PUBLIC LANDS AND SHORE LANDS - WORK PERMITS AND EXEMPTIONS — under the Public Lands Act

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

Ontario has consolidated a series of previously announced amendments to the public lands work permit regulation into the main text. Key practical changes include: the definition of 'shore lands' is now based on the high-water mark (not just seasonal inundation), with a new clarification that spring freshet or extreme flooding alone does not make land 'shore lands'; the term 'water crossing' is replaced throughout by the specific terms 'bridge, culvert or causeway'; and the old paper-based notice-of-activity form system for several exempt activities (building on mining claims, erosion control structure repair, etc.) is replaced by an online geographic-point registration process, with work allowed to start 10 days after Ministry confirmation rather than upon receipt of the form. Two new mandatory duties apply to anyone carrying out regulated activities on public lands: all work must stop immediately if an artifact is discovered and the Ministry must be notified by email, and all work must stop if human remains are found and police or a coroner must be notified. A new permit-free exemption is added for geotechnical investigations by test pit, trench or borehole where specified conditions are met. Operators planning dredging, filling, erosion control, vegetation removal, building placement on mining claims, or trail and road construction on public lands should review the updated registration requirements and new stop-work obligations before commencing work.

Who this affects: waterfront property owners · mining claim holders · construction and infrastructure operators on public lands · geotechnical investigators · forestry operators
