Founded in 1947 as Dominion Wildlife Service, it is Canada's national wildlife agency responsible for the protection and management of migratory birds, endangered species and nationally important wildlife habitats. November 1, 2012 marked the 65th anniversary of the founding of Service (originally known as the Dominion Wildlife Service). CWS conducts scientific research and monitoring, develops policies and regulations, manages permits, and provides financial and technical support for conservation programs. It manages 54 national wildlife areas and 92 migratory bird sanctuaries across Canada and plays a key role in implementing federal legislation, such as the Migratory Birds Convention Act, the

Biologists employed by the Canadian Wildlife Service also review environmental assessments, and review and issue permits under the Migratory Bird Regulations, Migratory Bird Sanctuary Regulations, Wildlife Area Regulations, and Species at Risk Act. Prior to 2006 the Canadian Wildlife Service was also home to wildlife research and enforcement staff.

History

CWS traces its history to the early 20th century with the decline and/or extinction of several species of migratory birds in eastern North America as a result of
hunting Hunting is the Human activity, human practice of seeking, pursuing, capturing, and killing wildlife or feral animals. The most common reasons for humans to hunt are to obtain the animal's body for meat and useful animal products (fur/hide (sk ...

. It became apparent to the federal government that the provincial responsibilities toward hunting regulation of migratory birds by various sub-national jurisdictions (provinces in Canada, states in the United States) was limited in scope. In 1916, Great Britain (for Canada) and the United States of America signed the "Migratory Birds Convention", followed by the

passing the Migratory Birds Convention Act in 1917, which gave the federal government responsibility for managing migratory bird species either harmless or beneficial to man. The Convention adopted a uniform system of protection for certain species of birds which migrate between the United States and Canada, in order to assure the preservation of species including setting dates for closed seasons on migratory birds and prohibiting hunting insectivorous birds, but allowed killing of birds under permit when injurious to agriculture. The Convention was amended by the Parksville protocol (initialled by the parties in 1995) to update and improve the conservation of migratory birds and to establish a legal framework for the subsistence take of birds. Canada implemented the Protocol by enacting the revised Migratory Birds Convention Act, 1994. With the federal government's reorganization of the Department of Resources and Development, the Dominion Wildlife Service (DWS), was established in November 1947. As a part of the new Lands and Development Services Branch, it was not meant to be as much of a research organization, but a "development and administrative service." The DWS dealt with policy and methods in the conservation and management of wildlife resources. "Few people in the 1940s saw wildlife from a holistic point of view. Like trees, birds, mammals, and fish were generally viewed a resources to be responsibly managed for the purpose of generating long-terms economic returns." Wildlife was a national asset. By 1950 the DWS was known as the Canadian Wildlife Service (CWS). Harrison Lewis was the first head of the new service, remaining in that post until his retirement in 1952. When the CWS was founded, important research on wildlife had been undertaken through the
National Museum of Canada The national museums of Canada () are the nine museums in Canada designated under the federal ''Museums Act'' and operated by the Government of Canada. The national museums are responsible for "preserving and promoting the heritage of Canada and al ...
. After 1947, CWS scientists and technicians earned recognition for research including work on migratory birds, particularly waterfowl and sea birds, in addition to barren-ground caribou and polar bears in the northern territories. Although Last Mountain Lake Bird Sanctuary in Saskatchewan was first created in 1887, many Migratory Bird Sanctuaries were established in the 1950s and 60s, and National Wildlife Areas in the 1960s and 70s. In 1973 the Canada Wildlife Act was passed, giving the federal government clear authority to undertake wildlife research, acquire lands for wildlife conservation, and deliver interpretation activities. Significant growth of the organization occurred during this period, and CWS began providing broader wildlife research and management services to National Parks. In the 1960s, 1970s and into the early 1980s, Canadian Wildlife Service produced '' Hinterland Who's Who'', a successful series of 60-second educational public-service television clips about Canada's native wildlife. The first four black-and-white vignettes - on the beaver, the moose, the gannet, and the loon - were produced through a collaboration with the

and the CWS. The vignettes resulted in millions of pamphlets about wildlife being mailed in response to viewers' requests to CWS. Individual Canadian Wildlife Service scientists and biologists became renowned for their work in conservation. Ernie Kuyt became well known for his pioneering work on the recovery of Whooping Cranes in Wood Buffalo National Park.

) was created. Environmental movements of that time encouraged a move away from the protection of individual species, towards a more holistic approach of protecting various ecosystems and the species that inhabited them. With the signing of the 1974 Canada-USA Great Lakes Water Quality Agreement, more funding became available. By 1975 David Peakall as WSC Division Chief was focusing his work on persistent bioaccumulatory organochlorines such as DDT, dieldrin and PCBs. The North American Waterfowl Management Plan (1986) lead to greatly increased funding and partnerships with Ducks Unlimited Canada and the Provinces to protect and enhance upland and wetland habitats for waterfowl, primarily in the Prairie Provinces. The

(1990) and Canadian Environmental Assessment Act (1994) further supported a need for toxicological research on waterbirds and aquatic ecosystems to support regulations and development decisions.

. In spite of these increased responsibilities and public awareness, there were deep budget cuts in the 1980s that reduced CWS budgets and reduced staff by 23%. Later austerity budgeting in 1994 lead to more restructuring and elimination of vacant positions. The Fisheries Act (1986) transferred some responsibilities for aquatic ecosystem research to the Department of Fisheries and Oceans, but Canadian Wildlife Service also retracted from servicing the National Parks, cut caribou research in the Arctic, several interpretive centers opened in the early 1980s were closed by the late 1980s, and growth of the National Wildlife Areas and Migratory Bird Sanctuaries effectively ended during this period of time.


SARA and Restructuring (2002–2006)

By 2006 the Canadian Wildlife Service had been restructured, with research scientists and enforcement officers moved to other Branches of Environment Canada. Publication series and public outreach functions were discontinued, and centralized control of communications reduced the freedom and frequency of CWS staff speaking at conferences or to the media. Attempts were made to eliminate the name "Canadian Wildlife Service" to something that reflected a broader role in biodiversity conservation, and the logo of the Loon adopted in the early 1980s was banned for use in official communications. By 2010 the Canadian Wildlife Service no longer had a homepage on-line, despite still existing as an organizational unit within Environment Canada (now
