Oak Ridges Moraine Land Use Designations Under Ontario Regulation

Land use designations form the legal basis for Ontario Regulation 140/02 governing the Oak Ridges Moraine. The Government of Ontario created this dataset by digitizing information from 0.5 metre aerial photography, official plans, and other digital vector layers. It was last updated in March 2026.

Use Cases

• Analyze land use designations to assess compliance with Ontario Regulation 140/02.
• Map designated land use polygons against current development proposals for environmental impact studies.
• Integrate digitized land use layers with other geospatial data for regional conservation modeling.

Strengths

• Digitized at a high spatial resolution of 1:10,000 or better.
• Derived from detailed 0.5 metre aerial photography and official municipal plans.
• Serves as the definitive basis for a specific provincial regulation (140/02).

Limitations

• Specific row and column counts, data volume, and sample data are unavailable for review.
• The dataset's internal structure and attribute fields are not described.
• Potential for temporal staleness if underlying source plans are not frequently updated.
