Part 1: Overview

Many species in Canada have not yet been assessed by COSEWIC, but are suspected of being at some risk of extinction or extirpation. These species, referred to as ‘candidate wildlife species’ are identified by the Species Specialist Subcommittees (SSCs) or by the Aboriginal Traditional Knowledge (ATK) Subcommittee as candidates for detailed status assessment. Candidates may also include wildlife species already assessed by COSEWIC as Not at Risk or Data Deficient, but where new information suggests they may be at risk.

SSC and ATK Subcommittee members use their expert knowledge and judgment to identify candidate wildlife species. They draw on numerous sources of information including (where available) the General Status of Wild Species in Canada Program, information drawn from other multi-jurisdictional monitoring, jurisdictional and international assessment processes (e.g. IUCN and ABI) and published ranking systems in the scientific literature. As time and resources allow, COSEWIC will commission status reports for high priority candidate wildlife species so that an assessment can be undertaken.

Status reports are commissioned by COSEWIC through an open competition. A Call for Bids is periodically posted on this website both for selected candidate species, and also for species already assessed by COSEWIC that require a reassessment. You can register to be notified when new Calls for Bids are posted on the website.

For more information on candidate wildlife species, visit the COSEWIC's Assessment Process and Criteria.


Part 2: The COSEWIC Candidate List

The highest priority wildlife species from the SSC candidate lists are reviewed and ranked by COSEWIC, and result in the COSEWIC Candidate List. COSEWIC bases its ranking on prioritization data submitted by each SSC (Prioritization Criteria developed by COSEWIC for ranking wildlife species). The COSEWIC Candidate List identifies the highest priority candidate wildlife species for status report production. Wildlife species included in this List include those not yet assessed by COSEWIC and those in the Not at Risk or Data Deficient categories, where new information suggests they may be at risk of extinction or extirpation from Canada.

Part 3: The Species Specialist Subcommittees’ (SSC) Candidate Lists

Each SSC annually prepares and maintains a SSC candidate list of wildlife species that it considers at risk of extinction or extirpation nationally. Species on the SSC candidate lists are ranked into three priority groups by the SSCs to reflect the relative urgency with which each wildlife species should receive a COSEWIC assessment. Group 1 contains wildlife species of highest priority for assessment by COSEWIC, and includes wildlife species suspected to be extirpated from Canada. Groups 2 and 3 contain wildlife species that are of intermediate and lower priority for COSEWIC assessment, respectively. Rationales for inclusion of wildlife species on the SSC candidate lists differ among the taxonomic groups considered by COSEWIC, reflecting the vast differences in their life history, and differences in our knowledge about the species.

The provinces or territories marked with † represent areas where the wildlife species is especially at risk. Wildlife species marked with one asterisk (*) were included on the Fall 2015 Call for Bids whereas those marked with two asterisks (**) will be included on the Fall 2016 Call for Bids.

Vascular Plants

An expanded Vascular Plants candidate list of over 500 vascular plants, grouped into two priority classes, is now available to the public in html or as an Excel worksheet file on the following link (Working List of Prioritized Vascular Plant Candidates). This list is provided with the understanding that it is a working copy undergoing modification. In preparing the list, information from the General Status of Species in Canada Review process, undertaken by all federal, provincial and territorial jurisdictions, is taken into account when species are ranked for inclusion on the list.
