Site assessments

The Evaluation Process can include:


PHASE I – Historical and background records review, site inspection, interviews and analysis to determine potential contamination on or near the site


PHASE II – Assessment of potential concerns through sample collection and analysis of suspect materials or contamination.


PHASE III – Formulation and completion of remediation plans or site management measures.


Currently Environmental Site Assessments (ESA) are used by clients involved in real estate transactions to determine potential or actual contamination on properties which could create financial liability.  Clients include vendors, financiers, purchasers, lawyers and real estate agents.  ESA’s have become a standard service when property ownership is transferred or land-use zoning is changed on some property types.  Canadian INvironmental Services (CIS) can provide an in-depth evaluation of the property according to the ESA guidelines required by Ontario Regulation 153/0, as amended, – Records of Site Condition under the Environmental Protection Act. .


What we do

Phase I

Phase II

Phase III

ESA - PHASE I - under the guidance of a Qualified Person (QP) this phase involves inspection and evaluation of a property to determine if actual or potential contamination exists on a property.  This is used to establish whether environmental problems may be present which could create financial liability and affect the value of the property.  The practice employed Canadian INvironmental Services is in general accordance with CSA Standard Z768-01 Phase I Environmental Site Assessment.   The initial investigation will identify the current status of the property gathering information that is reasonably accessible and/or obtainable through non-invasive procedures.

ESA - PHASE II - Using the findings and recommendations of the PHASE I, a PHASE II may be conducted to verify, disprove or delineate potential contamination on the property.  The information gathered during this phase will provide guidance in deciding a scope of work for investigation. PHASE II are conducted in accordance with the general requirements of the Canadian Standards Association (CSA) Standard Z769-00, Phase II Environmental Site Assessment.


CIS is capable of performing phase I and II ESAs as per requirements of amended Ontario Regulation 153/04. If any concerns are identified, remedial actions will be implemented based on findings of PHASE I and PHASE II assessments

PHASE III - Will involve some form of remedial action and may range from simple excavation of contaminated soil to implementation of bio-remediation programs or site-specific risk assessments and engineering solutions to reduce hazards.




Exposure Control includes site management measures designed and implemented to ensure that exposures do not result in human and ecological risks in excess of levels considered acceptable. Exposure Control may include long-term risk management options that are designed to eventually meet a Tier 1 or Tier 2 objective.


Exposure Control is required when contamination exceeds AEP Tier 1 or Tier 2 Guidelines where measures to preserve the site conditions or exposure assumptions are required to obtain acceptable risk levels, or otherwise to limit exposure to acceptable levels.


This includes oversight management of the property as it is brought to increasing utilization.


Exposure Control


Our world is changing day by day as environmental issues continue to impact

the planet. As a result our society has an ever increasing need to find more and more

sustainable ways of living. This sustainability involves examining our consumption and production of excessive goods and services. Included in this consumption is the

availability of the materials we use to build our schools, banks, homes etc.



Done Right

Building Sustainability Environmental design Part of building science is the attempt to design buildings with consideration for the future and the resources and realities of tomorrow.
