1996, presented his work on PCBs and the environment to the Organisation for Economic Co-operation and Development (OECD). David B. Peakall contributed to the OECD's adoption of "Minimum Pre-market Data" criteria regarding common standards for regulation and approval of new pesticides. In the 1970s the Department of the Environment 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 Canadian Environmental Protection Act (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 1976 the Committee on the Status of Endangered Wildlife in Canada brought together experts in all taxa from across the country and began preparing lists of species at risk using criteria consistent with the International Union for the Conservation of Nature. By the late 1990s there was political support for a national endangered species law, and in 2002 the Accord for the Protection of Species At Risk in Canada was a precursor to the Species At Risk Act. 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.
