You can comment on the ministry review of the amended St. Marys Future Solid Waste Disposal Needs Environmental Assessment until 5:00 p.m. on July 7, 2023.
The Town of St. Marys (town) is proposing to add 708,000 cubic metres (m3) of waste disposal capacity to the St. Marys landfill. This will allow the town to continue providing post-diversion municipal solid waste disposal services to St. Marys’ residents and its industrial, commercial and institutional sector until 2056.
The town has submitted an amended environmental assessment for this project. The assessment looks at how the proposed landfill expansion could impact the environment.

Amended environmental assessment
An invitation to comment on the St. Marys Future Solid Waste Disposal Needs Environmental Assessment was posted on Ontario’s environmental assessment webpage on August 12, 2021 for a seven-week period, closing October 1, 2021.
In response to the comments received, an amended environmental assessment was submitted to the ministry by the town on November 11, 2022.
The proposed undertaking identified in the amended environmental assessment includes both a vertical and horizontal expansion of the landfill to provide an additional 708,000 m3 of waste disposal capacity. The current landfill footprint of 8 hectares (ha) would be expanded by 3.2 ha, for a total footprint of 11.2 ha.
The proposed landfill expansion would require:
- realignment of a 230-metre section of a watercourse
- extension of the existing leachate collection system
- replacement of two existing stormwater management basins
The existing haul routes and site entrance would continue to be used, providing access to:
- new landfill access and maintenance roads
- a relocated public drop-off and scale house on-site
If approval to proceed is given for the undertaking, the landfill expansion must be carried out in accordance with the amended environmental assessment, subject to any conditions of approval, and would include the work outlined above. The town would also need to obtain all other permits and approvals it may require for the undertaking.
Notice of completion of ministry review
The ministry has prepared a review of the amended environmental assessment for Indigenous community, public and agency comment.
The review of the amended environmental assessment is not the decision on the undertaking, nor does it recommend a specific decision on the environmental assessment.
The decision whether to give approval to proceed with the undertaking would be made by the Minister of the Environment, Conservation and Parks after the comment period is over and any submissions have been considered. The minister’s decision is subject to the approval of the Lieutenant Governor in Council.
