Species At Risk

How to incorporate species at risk into what you do

Whether you help to plan, manage, consult on or work directly on projects or operational activities, your role is to keep things on track. That includes knowing how the Endangered Species Act may apply to your situation, how it may influence your planning, and what steps to take to make sure your plans comply with it.


Since the act is comprehensive and covers over 200 species, figuring out how it applies may not always seem simple. Situations vary by activity and species, but also by location and season in relation to species’ breeding, migration and other life stages. That’s why your best resource is practical guidance, both from this website and the Ministry of Natural Resources. Ministry staff can help you understand how the act applies to different scenarios and develop localized strategies that make the most sense for your activity and the species.

Planning activities with the act in mind

Complying with the act can influence your project design, parameters and timelines. Knowing early on about species at risk that may use your site is key to effective project planning. Start by identifying which species are in your area and their status, and learn about how they could affect your plans.

Figuring out if you need an authorization, like a permit or an agreement, starts with identifying which protected species are in your area.

Understanding permits and other authorizations


How do I know if I need a permit?

Different activities and locations can trigger the need for different permits. Every situation and site is unique, which is why we have permits to address many scenarios. In some cases, your activity may not require a permit but it may still be subject to other kinds of authorizations or regulations. It depends on whether your plans might have an adverse effect on a protected species or its habitat, and what you can do to avoid or reduce that impact.
