    • Permit to Take Water (surface)
    • Habitat Restoration and Channel Relocation
    • Tree Assessment
    • Fisheries Act Permits
    • Expert Witness

Toxicology & Risk Assessment

We are leaders in providing toxicology and risk assessment services to both public and private sector clients. We help our clients overcome obstacles using environmental science methods that are performed by experienced professionals. Clients receive clear communications of our findings and are provided with scientifically defensible data that allows them to make informed decisions.

We have a strong reputation in our industry for technical quality, which is delivered by our team of experts who publish their work in peer-reviewed journals, present at conferences, and participate on government advisory committees.

The services listed below reflect our areas of expertise within the fields of toxicology and risk assessment.

We provide all of the services and expertise to investigate, understand and manage risks related to chemicals in the environment.

Our environmental science team evaluates risks to human and ecological receptors resulting from exposure to substances in various media. Risk Assessments can be used to identify if any unacceptable risks exist, and whether remediation or risk management measures are required to reduce exposure. They can also assist in the development of site-specific environmental quality targets that are protective of people and the environment. These assessments help developers and property owners to evaluate and consider various site development locations and environmental management options. We help our clients determine the appropriate type of risk assessment that will achieve their project objectives.

Examples of risk assessment solutions that MTE provides include:

    • Risk Assessment submissions to the Ontario Ministry of the Environment, Conservation and Parks (MECP) for the purpose of obtaining a Record of Site Condition (RSC) under Ontario Regulation 153/04
      • Tier 3 Risk Assessment
      • Modified Generic Risk Assessment (MGRA)
    • Risk Assessments for due diligence purposes (e.g., in support of property transactions and financing)
    • Risk Assessments for federally-owned properties in accordance with Health Canada and the Canadian Council of Ministers of the Environment (CCME) guidance
      • Preliminary Quantitative Risk Assessment (PQRA)
      • Detailed Quantitative Risk Assessment (DQRA)
    • Vapour Intrusion Assessments

We can also develop and deliver basic or detailed human health and ecological risk assessment training courses to suit the specific needs of our clients in the private or public sector.

Increasingly, government agencies, corporations and other service providers are required to protect against impacts to the environment and human health. However, without the necessary scientific expertise and knowledge of regulations, this can be a complex, costly and time-consuming process.

Our environmental science team helps our clients effectively integrate regulatory requirements and scientific information to promote informed decision making. Since 1992, Canadian, American and international corporations, government agencies, and not-for-profit organizations have relied on us to help them identify, assess, apply and effectively communicate the information that is most critical to managing their toxicology-related issues.

Our Toxicologists provide expertise in the following areas:

    • Maximum Concentration Level Assessments (MCLAs)
    • Chemical Risk Assessment
    • Research and literature review to support updating of standards
    • Development of new and updated toxicology profiles
    • Litigation Support
    • Development of health-based standards and exposure limits
    • Development of site-specific benchmarks for ecological protection

We review technical documents produced by other scientists, including risk assessments, toxicological profiles and regulatory guidance documents. Our reviews on behalf of our industry and government clients focus on evaluating documents with respect to:

    • Appropriateness of scientific methods or approach used
    • Ensuring that cited information is complete and up-to-date
    • Consistency with cited regulatory guidance
    • Fulfillment of stated objectives
    • Appropriateness of conclusions and recommendations
    • Appropriateness of writing style for the target audience

We believe that our role as peer reviewers is to bring an independent eye to a document, and to look for opportunities to suggest changes which make the document more scientifically defensible, more transparent, or more complete. We have a reputation for being constructive peer reviewers whose involvement contributes positively to the projects we are involved in.

Stormwater management ponds are often inhabited by fish due to connections with adjacent natural water sources or through public introduction. Stormwater management ponds may also provide suitable habitat to support wildlife such as turtles and frogs. Following best management practices detailed by the Ministry of Natural Resources and Forestry (MNRF) for stormwater management pond clean-outs, fish and wildlife should be removed prior to clean-out activities being carried out.

MTE helps our clients obtain MNRF licenses and authorizations that are required to capture or handle fish and wildlife present within stormwater management ponds, as well as complete the removal of fish prior to pond clean-out. MTE also provides fish capturing and handling services for clients conducting other activities which may impact fish habitat such as culvert repairs.

MTE has the experience to effectively communicate complex scientific information to a variety of audiences. Our risk communication services ensure that stakeholders are appropriately informed about potential hazards and the risks that can affect people and the environment. We help our clients understand the risk assessment process and help stakeholders make informed decisions related to risk management. Our team understands that the ideal means of risk communication occurs when stakeholders are educated and enabled to participate in finding solutions to potential concerns.
