Licensed Tile Drainage Areas in Ontario

Ontario tile drainage areas installed by licensed contractors are reported to the provincial ministry. Locations are collected as a requirement for contractor licensing. The dataset is maintained by the Government of Ontario and was last updated in March 2026.

Use Cases

• Analyze spatial distribution of tile_drainage_area to identify regional agricultural water management practices.
• Model subsurface water flow by correlating drainage_tile_locations with soil type and precipitation data.
• Assess land use change by comparing reported tile_drainage_area installations over time.

Strengths

• Data is sourced from mandatory reports by licensed_agricultural_drainage_contractors, ensuring a degree of completeness.
• Maintained by a government authority (Ontario Ministry of Agriculture, Food, and Agribusiness).

Limitations

• Specific data volume (row count, spatial extent) and column definitions are unknown.
• Data is provided only in HTML format, which is not ideal for direct geospatial analysis.
