York Region Environmental Monitoring and Enforcement Group offers historical sewer use data for use by third party Environmental Site Assessments (ESA).

This service identifies if York Region has any relevant environmental information about a specific property. For example:

• Is the property currently monitored for sewer use bylaw purposes or had past infractions?
• Have there been any spills at the property?
• Is the property located in a drinking water source protection area of concern?

Eligibility

ESA data requests may only be made for properties located within York Region
