Trusted Environmental Expertise by Canadian Shield Consulting Agency

Before any land development, purchase, or construction project begins in Ontario, understanding the environmental condition of your site is essential. At Canadian Shield Consulting Agency, we provide professional Engineering Environmental Site Assessments (ESAs) to help property owners, real estate developers, and municipalities make informed, compliant decisions.

Our ESA services combine engineering precision with environmental expertise—ensuring your site meets all Ontario environmental regulations while minimizing risk, protecting property value, and safeguarding natural ecosystems.

What Is an Environmental Site Assessment (ESA)?

An Environmental Site Assessment (ESA) is a detailed study that evaluates the potential presence of contamination on a property. These assessments are crucial during real estate transactions, redevelopment projects, and regulatory compliance processes.

Canadian Shield Consulting Agency conducts Phase I, Phase II, and Phase III ESAs following CSA (Canadian Standards Association) and Ontario Ministry of the Environment, Conservation and Parks (MECP) guidelines.

Our engineering-based approach provides clear, actionable data to help you move forward confidently with your project.

Phase I Environmental Site Assessment (ESA)

A Phase I ESA is the first step in identifying potential or existing environmental contamination liabilities.

Our process includes:

• Historical property and land use research

• Review of government environmental databases

• Site inspection and photographic documentation

• Interviews with owners, occupants, and local officials

• Comprehensive reporting for lenders, developers, or investors

A Phase I ESA helps determine whether further investigation (Phase II) is needed. It’s a key requirement for most commercial property transactions in Ontario.

Phase II Environmental Site Assessment (ESA)

If contamination is suspected, a Phase II ESA involves sampling and laboratory analysis to confirm the presence and extent of pollutants.

Our engineering and environmental specialists collect and analyze soil, groundwater, and surface water samples using state-of-the-art methods.

We evaluate contaminants such as:

• Petroleum hydrocarbons (PHCs)

• Volatile organic compounds (VOCs)

• Heavy metals and nutrients

• Polychlorinated biphenyls (PCBs)

The results allow property owners and developers to make informed decisions about remediation, redevelopment, or further environmental planning.

Phase III Environmental Site Assessment & Remediation

If contamination is confirmed, Canadian Shield Consulting Agency provides Phase III ESA services that include detailed remediation planning and engineering oversight.

Our Phase III ESA solutions include:

• Contaminant delineation and risk assessment

• Soil and groundwater remediation design

• Contaminated site management

• Environmental monitoring and validation reporting

We work with clients to create cost-effective, compliant remediation plans that satisfy both environmental and development requirements under Ontario law.
