Environmental Site AssessmentsThat Protect What You're Buying.
Contamination does not appear on a title search. It sits in the soil, quietly attached to whoever holds title and the liability that comes with it does not always stay with the party that caused it. Envirolead delivers Phase 1 and Phase 2 ESAs across Alberta, British Columbia, Saskatchewan, and Manitoba that give buyers, lenders, and developers a clear picture of what they are actually acquiring.
There Are Environmental Risks That Don't Show Up on a Title Search
A property that looks clean and ready for development may have decades of industrial activity behind it fuel storage, chemical handling, vehicle maintenance. None of that surfaces unless someone looks for it. That is precisely what an Environmental Site Assessment is designed to do. It answers the questions a lender, buyer, or developer needs answered before committing capital: what is the environmental condition of this site, and what risk does it carry?
Why this matters for your transaction: Under Canadian environmental law, liability for contamination travels with the property not with the seller. A buyer who closes without conducting proper due diligence can inherit full responsibility for contamination they never caused. An ESA is how that risk is identified and addressed before it transfers.
Most institutional lenders across Alberta and British Columbia require a Phase I ESA before advancing funds on commercial or industrial property. For buyers, it is the difference between a clear picture of what they are acquiring and an expensive post-closing problem. For developers in Calgary, Edmonton, Vancouver, or anywhere across Western Canada, it affects site planning, cost projections, and regulatory timelines from day one.

Phase I & Phase II ESA What Each Involves
Every assessment Envirolead delivers is designed around the property in front of us not a generic template applied uniformly across different sites. Here is what each phase of the process involves.
Phase I ESA Non-Intrusive, Fully Documented Environmental Due Diligence
A Phase I ESA is the starting point for environmental due diligence on any commercial or industrial property transaction. It is non-intrusive no drilling, no sampling, no laboratory work. What it does involve is a thorough, disciplined investigation into the property's history and current condition, carried out by certified environmental professionals who know what to look for and where to find it.
Banks require it before approving financing. Regulators across Alberta and BC expect it before development approvals. And any buyer who has been through a transaction that went sideways because of undisclosed contamination will tell you they wish they had insisted on one, regardless of what anyone required of them at the time.
Every Phase I ESA Envirolead produces is conducted in accordance with CSA Standard Z768-01 and aligned with ASTM E1527-21 where lenders require it. Our reports are prepared to the submission standards of major Canadian financial institutions and they do not come back for revision.
Phase I ESA Process Step by Step
Project Scoping & File Opening
Property details confirmed, scope of work defined, and CSA/ASTM standard selected based on lender and regulatory requirements.
Historical Research
Records review covering land titles, aerial photographs, city directories, fire insurance plans, and all available historical documentation on the property's past use.
Regulatory & Database Search
Federal and provincial environmental database searches, UST registries, spill records, and regulatory correspondence files for the subject property and adjacent lands.
Site Reconnaissance
Physical inspection of the property by a certified QEP observing, documenting, and photographing all relevant conditions and potential indicators of environmental concern.
Interviews
Conversations with owners, operators, and others with knowledge of the property's history to capture information that records alone do not provide.
Report Preparation & Delivery
CSA/ASTM-compliant Phase I ESA report prepared, internally reviewed, and delivered typically within 1 to 3 weeks of project initiation, structured to meet lender and regulatory submission standards.
What a Phase I ESA Report Covers
Historical Records Review
Land titles, ownership history, aerial photographs analysed across multiple time periods, and city directory records tracing past land use back decades.
Environmental Database Search
Federal and provincial database searches covering spill records, underground storage tanks, regulatory orders, and known contamination on and around the subject property.
Site Reconnaissance
A physical inspection of the property and surrounding area by a qualified environmental professional looking for staining, distressed vegetation, odours, storage tanks, and other observable indicators of concern.
Interviews
Where possible, direct conversations with people who have knowledge of the property's history. Small details from those conversations sometimes change the direction of an assessment entirely.
Adjoining Property Review
Evaluation of neighbouring land uses and their potential to impact the subject site because contamination from adjacent properties does not respect property lines.
REC Identification & Recommendations
Clear statement of any Recognized Environmental Conditions identified, what they are based on, and the recommended next step for the client and their transaction.
Understanding REC Outcomes
The Phase I ESA report is organised around the identification of Recognized Environmental Conditions. Finding a REC does not automatically mean a property is contaminated it means there is enough evidence of potential risk to warrant further investigation before the transaction proceeds.
✅ No RECs Identified
No evidence of environmental concern. Transaction can proceed with confidence. Report supports lender environmental clearance requirements.
⚠ RECs Identified
Evidence of potential contamination risk. A Phase II ESA is recommended to confirm or rule out contamination through subsurface investigation.
🔴 Significant RECs
Evidence strongly indicates contamination is present. Phase II ESA and potentially remediation planning required before the transaction can close.
Phase II ESA Subsurface Investigation That Confirms or Clears Contamination
When a Phase I ESA identifies Recognized Environmental Conditions, or when a lender or regulator requires confirmation of site conditions before a transaction proceeds, a Phase II Environmental Site Assessment is the next step. This is where the investigation moves from research to fieldwork.
Soil is sampled. Boreholes are drilled. Groundwater monitoring wells are installed where subsurface water conditions require it. Samples go to accredited laboratories. The results come back and are interpreted by environmental professionals who understand what they mean not just what the numbers say, but what they indicate about the property and what needs to happen next.
No two Phase II investigations look exactly the same. The scope is built around what the Phase I found: the nature of the suspected contamination, where it likely originated, and how it may have migrated through the subsurface over time. A generic investigation applied uniformly to different sites produces results that are technically adequate and practically limited. Envirolead designs every Phase II ESA specifically for the site.
Phase II ESA Process Step by Step
Investigation Design
Scope built around Phase I findings contaminant type, suspected source locations, and likely migration pathways determine borehole placement and sampling strategy.
Health & Safety Planning
Site-specific health and safety plan prepared for field activities. All fieldwork conducted in compliance with provincial OHS requirements across Alberta, BC, Saskatchewan, and Manitoba.
Field Investigation
Borehole drilling, test pit excavation, monitoring well installation, and sample collection documented in real time with chain-of-custody protocols maintained throughout.
Laboratory Analysis
Samples submitted to accredited environmental testing facilities. Results reviewed against applicable Alberta and provincial regulatory criteria upon receipt.
Data Interpretation
Laboratory results interpreted in site-specific context identifying contamination sources, lateral and vertical extent, and risk implications for the property and any adjacent receptors.
Report & Regulatory Submission
Phase II ESA report prepared and internally reviewed. In Alberta, findings feed directly into Records of Site Condition submissions under EPEA Section 35. Envirolead manages that process from investigation through to regulatory filing.
What a Phase II ESA Involves
Borehole Drilling & Test Pits
Targeted borehole drilling and test pit excavation at locations selected based on Phase I findings not a generic grid pattern across the site.
Groundwater Monitoring Wells
Installation of monitoring wells where subsurface conditions require groundwater sampling with well construction documented to regulatory standards.
Soil & Groundwater Sampling
Collection of soil, groundwater, and soil vapour samples using established field protocols. All samples submitted to accredited environmental testing laboratories.
Regulatory Comparison
Laboratory results evaluated against Alberta Tier 1 & Tier 2 Soil and Groundwater Remediation Guidelines, CCME criteria, and applicable BC, Saskatchewan, and Manitoba provincial standards.
Subsurface Interpretation
Site plans and subsurface diagrams mapping contaminant distribution laterally and vertically so clients and regulators understand the full picture of site conditions.
Professional Conclusions & Recommendations
Clear professional opinion on contamination status, environmental risk, and the recommended path forward whether remediation, risk management, or no further action.

Built for Every Party in a Property Transaction
Environmental Site Assessments serve different purposes depending on where you sit in the transaction. Here is who Envirolead works with across Alberta, BC, Saskatchewan, and Manitoba and what the ESA protects for each of them.
Lenders & Financial Institutions
Most major Canadian banks and credit unions require a Phase I ESA before advancing funds on commercial or industrial properties. Envirolead's reports meet the submission standards of Canadian financial institutions and they do not generate the revision requests that slow loan approvals.
Property Buyers & Investors
Buying a commercial property in Calgary, Edmonton, Vancouver, or anywhere across Western Canada without an ESA is accepting environmental liability you cannot see. A Phase I ESA is how buyers understand what they are acquiring before the deal closes not after.
Developers & Builders
Environmental conditions affect site planning, construction costs, regulatory timelines, and development approvals. Envirolead works with developers from the initial Phase I through to Phase II investigations and, where required, into remediation and RSC submission across all four provinces.
Municipalities & Counties
Brownfield redevelopment across Alberta, Saskatchewan, and Manitoba requires environmental due diligence that meets both provincial regulatory requirements and PSAB 3260 public sector accounting standards for environmental liability. Envirolead has direct experience working with municipal clients on these programs.
Legal Counsel
Real estate transactions with environmental risk exposure require ESA reports that are defensible, professionally prepared, and clearly communicate what was found, how it was assessed, and what it means for the parties involved. Envirolead's reports are written to that standard.
Industrial & Commercial Owners
Properties with fuel station histories, manufacturing operations, or other industrial uses carry environmental liability that is not visible at the surface. Envirolead helps owners understand their exposure whether they are planning a sale, a refinancing, or simply want to understand what is on their land.
Standards & Regulations We Work Under
Every Envirolead ESA is conducted against the applicable standards and regulatory requirements of the province where the property is located. Our professionals stay current with changing regulatory requirements across all four provinces we serve.
CSA Z768-22
The Canadian standard for Phase I ESA practice. All Envirolead Phase I ESAs are conducted in accordance with CSA Z768-22 the standard recognized by Canadian lenders and provincial regulators.
ASTM E1527-21
American standard referenced by some Canadian lenders and cross-border transactions. Envirolead produces ASTM-aligned reports where lender requirements specify this standard.
CSA Z769-00
The Canadian standard governing Phase II ESA practice. All Envirolead Phase II investigations are conducted in accordance with CSA Z769-00, the standard recognized by Canadian lenders and provincial regulators.
ASTM E1903-19
American standard for Phase II ESA practice. Envirolead conducts subsurface investigations aligned with ASTM E1903-19 where lender requirements or cross-border transactions specify this standard.
Alberta EPEA
Environmental Protection and Enhancement Act. Governs environmental assessment and remediation requirements in Alberta. Phase II findings in Alberta feed into RSC submissions under EPEA Section 35.
Alberta Tier 1 & Tier 2
Alberta's Soil and Groundwater Remediation Guidelines the regulatory benchmark against which Phase II laboratory results are evaluated on every Alberta site.
CCME Guidelines
Canadian Council of Ministers of the Environment criteria applied as an additional benchmark across BC, Saskatchewan, and Manitoba projects where provincial standards reference CCME.
BC, SK & MB Regulations
Provincial environmental assessment and contaminated site regulations in British Columbia, Saskatchewan, and Manitoba applied on all Envirolead projects in those provinces.
What Clients Across Western Canada Rely On
Reports That Lenders Accept Without Revision
Envirolead's Phase I and Phase II ESA reports are prepared to the documentation standard that major Canadian financial institutions expect. Our Calgary and Edmonton clients return to us because their lenders do not send reports back for revision and that track record directly protects transaction timelines.
Investigations Designed for the Site Not a Template
A generic Phase II investigation applied uniformly to different sites produces results that are technically adequate and practically limited. Envirolead designs every Phase II ESA around what the Phase I actually found contaminant type, suspected source, and likely migration pathway to produce results that actually answer the question the client needs answered.
Transaction Timeline Awareness
Real estate transactions in Calgary, Edmonton, Vancouver, and across Western Canada have closing dates. Financing windows do not stay open indefinitely. Envirolead structures Phase I turnarounds with transaction timelines in mind and scopes Phase II investigations to avoid creating bottlenecks in approval and financing processes.
End-to-End Capability ESA Through to RSC
When a Phase II ESA confirms contamination, the next step is remediation and regulatory closure. Because Envirolead manages the full process Phase I, Phase II, Remediation Action Plan, and RSC submission clients do not have to bring in a different firm at the point where the work gets most complex. One team, one file, full accountability.
Frequently Asked Questions
Typically 1 to 3 weeks from project initiation. Turnaround depends on the complexity of the property's history and the availability of historical records. Envirolead structures Phase I timelines around transaction deadlines if you have a closing date, tell us and we will work to it.
A Phase I ESA is a non-intrusive records and site review no drilling, no sampling. It identifies Recognized Environmental Conditions based on the property's history. A Phase II ESA involves physical subsurface investigation boreholes, sampling, and lab analysis to confirm or rule out actual contamination.
Most major Canadian banks and credit unions require a Phase I ESA before advancing funds on commercial or industrial property. The specific standard they require (CSA Z768-01 or ASTM E1527-21) will be in their environmental due diligence policy. Envirolead produces reports that meet both standards.
A REC does not mean the property is contaminated it means there is enough evidence of potential risk to warrant further investigation. The recommended next step is a Phase II ESA to confirm or rule out contamination through subsurface sampling and laboratory analysis.
Yes Envirolead delivers Phase I and Phase II ESAs across Alberta, British Columbia, Saskatchewan, and Manitoba. Whether the property is in Vancouver, Winnipeg, Regina, or a rural agricultural location in Saskatchewan, the standard of work does not change based on geography.
Yes. Envirolead manages the full process from Phase I and Phase II ESA through to Remediation Action Plan development, remediation implementation, and Record of Site Condition submission in Alberta. Clients do not need to bring in a second firm when the work moves from investigation to remediation.
