Environmental Site Assessments (Phase I, II & III)

Regulatory-aligned assessments to support due diligence, liability management, and development decisions.

Environmental Site Assessments (Phase I, II & III)

Overview

We complete Phase I, II, and III Environmental Site Assessments (ESAs) in accordance with provincial and federal requirements, supporting residential, commercial, industrial, and oil and gas properties. Our experience also includes work within Parks Canada, where elevated environmental standards and regulatory complexity require a high level of technical rigor and accountability.

Our assessments provide defensible understanding of environmental conditions and potential liabilities, supporting due diligence, ARO evaluation, and development planning while maintaining alignment with regulatory expectations.

Our Approach

Each ESA is tailored to site-specific objectives and regulatory requirements. We focus on identifying potential concerns early, designing targeted investigations, and providing clear recommendations that support next steps.

Our team emphasizes practical outcomes, delivering assessments that not only meet regulatory standards but also help clients manage risk, plan development, or advance
sites toward closure with confidence.
