Development & Regulatory

Policies and regulations around land use are expanding increasingly due to a heightened interest in preserving our natural environment. As a result, studies that document and define impacts of proposed projects on the natural environment are routinely required for development submissions. McIntosh Perry conducts extensive natural science evaluations that catalogue biological inventories, assess impacts, ensure due diligence pertaining to client environmental liabilities, review baseline information, and meet and legislative/ministry requirements for land use projects.

Our deep understanding of these matters allows us to acquire faster regulatory approvals for our clients. We offer detailed studies and reports including as noted.

Environmental Impact Studies (EIS)

McIntosh Perry Natural Science professionals are experienced in carrying out EIS studies supporting a wide variety of undertakings including private development and severances, road/bridge and culvert infrastructure rehabilitation, large subdivisions, and commercial/institutional construction. Environmental Impact Studies (EIS) are an important part of the development planning process and identify the natural features and functions present on a site inclusive of wetlands, wildlife, fish habitat, migratory bird and vegetation inventories, Species at Risk (SAR), woodlands, valley lands, and Areas of Natural Scientific Interest (ANSI’s). Final EIS reports detail the potential impacts present on sites as well as addressing the required mitigations to protect sensitive features.  Through maximized communications with the client, conservation authorities, and Townships, McIntosh Perry staff consistently deliver EIS studies that address all stakeholder and client needs while being both on time and on budget. Our typical EIS process takes 2 – 4 months from start to report delivery.

McIntosh Perry will discuss the nature of your development, site features, agency requirements, conduct a preliminary review of your site, and provide a detailed proposal at no cost.

Tree Inventory Reports

Tree Inventory and Preservation Plans describe the condition of initial site vegetation, any impacts of proposed development, and associated mitigation measures to minimize impacts and preserve conserved trees. Our specialists prepare, collect, map, and analyze tree inventory data within study areas to better understand species composition and current tree condition. These plans also detail any compensation requirements for removed trees, provide recommendations to ensure tree survival and create a safe environment during the construction period, while also preserving the trees and ensuring that they do not become a hazard in the long-term. Speak with one of our professionals to discuss your project and how we can help developing a customized Tree Inventory/Preservation plan.

Level I & II Natural Environment Studies – Supporting Pits & Quarries

Permits are required for the development of quarries that allow for aggregate extraction both above and below the water table. McIntosh Perry Natural Sciences staff prepare Level 1 or 2 Natural Environment Reports (NER) that support this aggregate permitting process to identify the presence of any natural features or functions on or adjacent to sites.  A terrestrial audit of the site is generally conducted by our biologists and ecologists. Screening for specific Species at Risk (SAR) that utilize rocky habitat areas are also frequently conducted. A Level 1 general NER is completed initially. If any important sensitive features or functions are identified, typically a Level 2 study will be required for further study and to define specific impacts and recommended mitigations. We are experienced at meeting any reporting needs to support your aggregate extraction project.

Permit to Take Water

We are experienced in carrying out biophysical studies that support applications for Permits to Take Water in Ontario when required based on the nature of the proposed water taking. We work closely with our Geo-Environmental group to meet client needs.

Ontario has a wealth of freshwater resources that provide habitat for a multitude of aquatic species. Our professionals have an excellent working knowledge of legislation, guidelines, and policy developed for the protection of fish and fish habitat that may be impacted by proposed development, infrastructure, or other projects.

In order to assist with compliance with existing legislation by our clients we carry out assessments of existing conditions, define any impacts, and provide recommendations to reduce effects. We also carry our projects to improve fish habitat or passage by providing design recommendations.


Electrofishing is a non-harmful fishing technique used by field personnel to help identify or relocate fish present in waterbodies. McIntosh Perry stores state of the art electrofishing units at our offices across Ontario to be able to respond quickly to our clients needs and deploy resources into the field on short notice. Our field professionals are  both trained and certified to carry out electrofishing in support of a variety of projects where fishery related studies, inventories, or salvage may be required. We can also prepare the documentation and secure the required Scientific Collectors Permit required prior to carrying out electrofishing at your site.

Fish Salvage

For many infrastructure or other projects, in-water work may often be needed, thereby requiring the isolation of a work area within a watercourse. This necessitates the removal of fish from the working area and relocation to a safe area downstream prior to initiating any work. Our field professionals are trained and certified to carry out fish salvage and can provide all the services required to support any fish removal/relocation requirements for your project. Typically, the services summarized below are required.

Fish Removal Plan, MNRF Scientific Collector’s Permit, and Fish Removal Services:

  • Apply and obtain required a Ministry of Northern Development, Mines, Natural Resources and Forestry (NDMNRF) Scientific Collector’s Permit, including required Fish Collection Record reporting to NDMNRF); and
  • Fish Removal Services by qualified staff as per industry best practices, including any requirements by NDMNRF, Department of Fisheries and Oceans (DFO), any Local Conservation Authority
Existing Conditions and Impact Studies

McIntosh Perry biologists are frequently retained by both private and government clients to conduct in depth studies that characterize and document aquatic habitat conditions within study areas. Staff are skilled at preparing Existing Conditions and Related Impact/Mitigation reports that explore how a proposed development (both shoreline adjacent and in-water) might impact the area fish habitat and provide protection recommendations in our reporting. Our studies support a wide range of undertakings including provincial and municipal infrastructure, industrial, institutional, and private development projects.

Stream Habitat Assessments

Our staff are experienced in completing comprehensive watercourse habitat assessments for your project if required as a part of aquatic studies, restoration, or other works. We will carry out field investigations to map aquatic habitat features and values present within study areas inclusive of watercourse dimensions, in-stream cover, riparian and aquatic vegetation, substrate information, flow characteristics, sedimentation and pollutant point sources.

DFO – Request for Review (RFR) Preparations

Following an assessment, when a proposed undertaking is shown to potentially impact fish populations, a Fisheries and Oceans Canada (DFO) request for review may be needed. Our scientists can prepare the required documentation to support the Request for Review and communicate with agency staff to assist in securing approvals. We  work closely with regional DFO offices on a regular basis on behalf of our clients in an effort of supporting their submissions.

Benthic Studies

Benthic organisms are valuable indicators of water quality, as diverse populations present within the sediments of watercourses. Monitoring of benthic organisms both upstream and downstream of a targeted area can provide important information about the source of pollution/toxicity. The presence of pollution-tolerant benthic organisms is a strong indicator of good water quality; and inversely, pollution-tolerant benthic macro-invertebrate presence is associated with poor water quality. Our team can develop your monitoring program, carry out sampling, provide statistical analysis/interpretation of the data, and provide a comprehensive report detailing the results.

Fish Passage Evaluation & Design

Our biologists, ecologists, and scientist can assist you with any projects where fish passage must be optimized or where existing barriers to fish mobility have been identified. Our Natural Sciences team includes professionals with extensive experience in fish passage assessment and design. We work closely with our structural and drainage design teams and provide consultation regarding design modifications to enhance passage for example: assuring optimal watercourse flow for identified species, the need for baffle placement, or substrate quality enhancement.

Stream Restoration

At McIntosh Perry our multidisciplinary approach to watercourse restoration includes collaboration between  Natural Sciences, Water Resources, Environmental Engineering, and Geomorphology disciplines as the scope of projects can be complex including the establishment of riparian zones, native plantings, fish passage features, bank stabilization, substrate modification, etc. From large to smaller watercourse restoration projects, we are able to meet your needs.

Culvert Inspections

Our team can carry out in-field investigations to determine or confirm if watercourses that can be impacted by proposed infrastructure repair or replacement, represent fish habitat. As such, we would provide direction regarding the need for additional services i.e., permitting, construction timing windows, the need for electrofishing or fish salvage, or other recommendations/approvals.

Our avian biologists can also complete comprehensive avian studies that examine relationships between habitat factors, defined impacts, and cite mitigations.

Turtle Fence Design/Monitoring

Speak with us about designing, installing, and conducting monitoring for your Species at Risk turtle protection project. McIntosh Perry has managed the installation of many projects primarily in the Ottawa area.

Species At Risk (SAR) Surveys

McIntosh Perry specializes in conducting Species at Risk surveys for client projects. Typically, initial desktop background reviews of available information sources will be undertaken in order to provide data on any Species at Risk (SAR) present in the vicinity of the project area as well as local habitat conditions. Our biologist will then conduct in-field investigations to supplement this information. Pending findings McIntosh biologist may recommend additional targeted surveys.  Surveys may be for SAR reptiles, bats, birds, or amphibians pending the nature of the site habitat. Through reporting staff will detail next steps for the client.

Species At Risk (SAR) Municipal Mapping

Through collaboration with our GIS department, we are able to provide comprehensive mapping services of Species at Risk (SAR) habitat locations for governments, municipalities, and institutions and are able to align mapping formats for a seamless integration with client data resources. We have seen that the development of detailed maps of SAR occurrences can be extremely strong planning tools. Accordingly, infrastructure or construction projects can be designed to be outside of SAR habitats or critical timelines thereby saving time and resources.

Endangered Species Act Authorizations

McIntosh Perry ecologists understand the importance and intricacies of the Canadian Species At Risk Act (SARA) and the Ontario Endangered Species Act (ESA) that provide protections for identified SAR and their habitats. Pending your project requirements, in special cases, McIntosh Perry can help you to obtain Endangered Species Act permits and authorizations. These permits contain conditions that are aimed at protecting and recovering at-risk plants and animals. Should the need arise, we also assist clients with the completion of Information Gathering Forms (IGF) for SAR as required by the Ministry of Northern Development, Mines, Natural Resources and Forestry (NDMNRF).

Overall Benefit Permits/Habitat Compensation Design

McIntosh Perry Natural Science professionals have surveyed, located, selected, designed, and constructed many alternate habitat areas for species because of required compensation measures from projects where Overall Benefit Permits were issued. In addition to developing these specialized habitats at remote sites from the initial undertaking we have carried out routine monitoring to track the initiation and continued use of these habitat areas by protected species.

Wetland Surveys/Delineation

Canada has a multitude of wetlands inclusive of both unevaluated and provincially Significant Wetlands. Our team conducts field visits to characterize any wetlands present on client sites. We can also delineate and map the boundaries of site wetlands and provide feedback on any mandated setbacks from the boundaries that is important for land use or development issues.

Migratory Bird Site Screening

Our avian biologists can carry out breeding bird nesting sweeps required for any tree clearing activities planned within the breeding bird window roughly from April 1st to August 31st of any year. Should a nesting migratory bird be identified, we advise our clients with respect to any required setbacks or buffers to be observed and the anticipated fledging time. This provides our clients with a rough timeframe when the species is expected to have completed nesting and when work can continue.
