Whitby, Ontario developers planning redevelopment of potentially contaminated land must follow provincial and municipal processes for soil testing, remediation and documentation. This guide explains key steps: initial site screening, hiring a Qualified Person, laboratory testing, preparing a remediation plan, and filing a Record of Site Condition where required. It highlights municipal application paths in Whitby and the provincial RSC process so you know who enforces rules, what forms to file, and how to proceed from assessment to site closure.

Permits, testing and regulatory overview

Start with a Phase I Environmental Site Assessment to identify potential contamination and then a Phase II investigation if sampling is needed. For planning approvals and development applications in Whitby, contact Planning & Development Services for site-specific requirements and submission steps Town of Whitby Development Applications[1]. Provincial requirements for Records of Site Condition (RSC) and filing on the Environmental Site Registry are administered by the Ontario government Records of Site Condition (RSC) guidance[2]. The technical and legal basis for RSCs is set out in Ontario Regulation 153/04 O. Reg. 153/04[3].

Hire a Qualified Person early to reduce costs and regulatory delays.
