Critical Habitat Orders

  • Critical Habitat of the Western Brook Lamprey (Lampetra richardsoni) Morrison Creek Population Order: SOR/2019-123 (2019-05-15)
    The Western Brook Lamprey – Morrison Creek Population (Lampetra richardsoni) is a small freshwater fish endemic to the Morrison Creek watershed on eastern Vancouver Island, British Columbia. The species has a rare life history in which both a parasitic (L. richardsoni var. marifuga) type and a non-parasitic (L. richardsoni) type are produced. No quantitative population estimates exist for the Morrison Creek Lamprey; however, catch rates of the pa ...
  • Critical Habitat of the Hotwater Physa (Physella wrighti) Order: SOR/2019-21 (2019-02-06)
    The Hotwater Physa (Physella wrighti) is a small freshwater snail found only within the Liard River Hot Springs complex located in Liard River Hot Springs Provincial Park in northeastern British Columbia. While there is currently no evidence of a population decline, Hotwater Physa has a very small and localized distribution in Canada which makes it vulnerable to the risk of extinction due to human activities or catastrophic events.
  • Critical Habitat of the Coastrange Sculpin (Cottus aleuticus) Cultus Population Order: SOR/2019-3 (2019-01-09)
    The Coastrange Sculpin (Cottus aleuticus) Cultus population, hereafter referred to as the Cultus Pygmy Sculpin, is a small freshwater fish found only in Cultus Lake, a small lake located in the lower mainland region of southwestern British Columbia (BC). Available information on the abundance of Cultus Pygmy Sculpin is limited, but incidental catch data suggests a possible slight downward trend. In November 2000, the Committee on the Status of En ...

    The Western Silvery Minnow (Hybognathus argyritis) is a small cyprinid species native to northwestern North America. In Canada, the Western Silvery Minnow has only been confirmed in the Milk River in southern Alberta. In November 2001, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) assessed the status of the Western Silvery Minnow and classified the species as a threatened species. In June 2003, the Western Silvery Minnow ...
  • Critical Habitat of the Harbour Seal Lacs des Loups Marins subspecies (Phoca vitulina mellonae) Order: SOR/2018-268 (2018-12-26)
    The Harbour Seal, Lacs des Loups Marins subspecies (hereinafter referred to as Lacs des Loups Marins Harbour Seal), is a population endemic to Quebec, living exclusively in freshwater in a group of lakes and rivers located 250 km east of Hudson Bay in Nunavik. The population size is unknown, but it is estimated at between 50 and 600 individuals.
  • Critical Habitat of the Killer Whale (Orcinus orca) Northeast Pacific Northern Resident Population Order: SOR/2018-279 (2018-12-26)
    Subsection 58(1) of the Species at Risk Act applies to the critical habitat of the Killer Whale (Orcinus orca) Northeast Pacific northern resident population, which is identified in the recovery strategy for that species that is included in the Species at Risk Public Registry.
  • Critical Habitat of the Killer Whale (Orcinus orca) Northeast Pacific Southern Resident Population Order: SOR/2018-278 (2018-12-26)
    Two distinct populations of Resident Killer Whales (Orcinus orca) occupy the waters off the Pacific coast of Canada: the Northeast Pacific Southern Resident Killer Whale (SRKW) population and the Northeast Pacific Northern Resident Killer Whale (NRKW) population. Although the ranges of these two populations overlap, they are acoustically, culturally, and genetically distinct from each other. As of November 2018, the SRKW population consisted ...
  • Critical Habitat of the Woodland Caribou (Rangifer tarandus caribou) Boreal Population Order (2018-12-08)
    The boreal population of the Woodland Caribou (Rangifer tarandus caribou) is commonly called boreal caribou. Like all Woodland Caribou, boreal caribou are a medium-sized member of the deer family. Boreal caribou are distributed across Canada, occurring in seven provinces and two territories and extending from the northeast corner of Yukon east to Labrador, and south to Lake Superior in Ontario.
  • Critical Habitat of the Speckled Dace (Rhinichthys osculus) Order: SOR/2018-218 (2018-11-14)
    The Speckled Dace (Rhinichthys osculus) is a small freshwater fish that is widely distributed in rivers throughout western North America. In Canada, Speckled Dace occurs only in a short section of the Columbia River drainage in the Kootenay Boundary regional district of British Columbia. While this species is moderately abundant, its distribution in Canada is very restricted, suggesting that the Speckled Dace will continually be at some risk.
  • Critical Habitat of the Misty Lake Lentic Threespine Stickleback (Gasterosteus aculeatus) Order: SOR/2018-208 (2018-10-31)
    The Misty Lake Lentic Threespine Stickleback (Gasterosteus aculeatus) and the Misty Lake Lotic Threespine Stickleback (Gasterosteus aculeatus) [hereafter referred to as the Misty Lake Sticklebacks] are freshwater fishes that are restricted to a single lake-stream complex on northern Vancouver Island, British Columbia. In November 2006, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) assessed the status of the Misty Lake Sti ...
  • Critical Habitat of the Misty Lake Lotic Threespine Stickleback (Gasterosteus aculeatus) Order: SOR/2018-209 (2018-10-31)
    The Misty Lake Lentic Threespine Stickleback (Gasterosteus aculeatus) and the Misty Lake Lotic Threespine Stickleback (Gasterosteus aculeatus) [hereafter referred to as the Misty Lake Sticklebacks] are freshwater fishes that are restricted to a single lake-stream complex on northern Vancouver Island, British Columbia. In November 2006, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) assessed the status of the Misty Lake Sti ...
  • Critical Habitat of Atlantic Whitefish (Coregonus huntsmani) Order: SOR/2018-182 (2018-09-19)
    The Atlantic Whitefish (Coregonus huntsmani) is a Canadian endemic fish species known historically to occur in two watersheds in southwestern Nova Scotia. Once anadromous, the species has continued to decline in abundance and distribution, and presently occurs as a single lake-resident population distributed amongst three small, interconnected, semi-natural lakes in the Petite Rivière watershed. In this last remaining refuge, its status continues ...
  • Critical Habitat of Carmine Shiner (Notropis percobromus) Order: SOR/2018-183 (2018-09-19)
    The Carmine Shiner (Notropis percobromus) is found in the Whitemouth, Birch and Winnipeg river watersheds in Manitoba. While there is no evidence that Carmine Shiner populations have declined over time, because of its limited distribution and abundance, the species may be sensitive to future anthropogenic disturbances. In November 2001, and in April 2006, the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) assessed the status o ...
  • Critical Habitat of the Western Chorus Frog (Pseudacris triseriata) Great Lakes / St. Lawrence – Canadian Shield Population Order (2018-08-22)
    The objective of the Critical Habitat of the Western Chorus Frog (Pseudacris triseriata) Great Lakes / St. Lawrence – Canadian Shield Population Order (the Order) is to support the survival and recovery of Western Chorus Frog (GLSLCS) through the legal protection of its critical habitat on federally administered lands in Ontario and Quebec.
  • Critical Habitat of the Eastern Sand Darter (Ammocrypta pellucida) Quebec Populations Order (2018-07-25)
    The objective of the Recovery Strategy over the long term (20 years) is to promote the growth of existing populations to ensure their viability and, wherever possible, to restore historical populations that have disappeared. The short-term (within five years) objective of the Recovery Strategy is to maintain Eastern Sand Darter populations throughout the species’ distribution in Quebec and prevent their decline. Efforts to meet the short- and lon ...
