The Historic treaties (formerly known as the Pre-1975 treaties) dataset contains geographic boundaries as well as basic attribute data representing signed treaties that were negotiated between Indigenous peoples and the Crown between 1725 and 1929. However, the Treaties of Peace and Neutrality, signed between 1701 and 1760, are not represented in this dataset because they do not have geographic boundaries that can be represented on a map. Apart from the Peace and Friendship Treaties, these boundaries represent the historic treaties signed after 1763, which provided large areas of First Nations land, to the Crown (transferring their Aboriginal title to the Crown) in exchange for reserve lands and other benefits. The Government of Canada recognizes 70 historic treaties in Canada signed between 1701 and 1923. These treaties include: • Treaties of Peace and Neutrality (1701-1760) • Peace and Friendship Treaties (1725-1779) • Upper Canada Land Surrenders and the Williams Treaties (1764-1862/1923) • Robinson Treaties and Douglas Treaties (1850-1854) • The Numbered Treaties (1871-1921) These boundaries are usually not surveyed but help to delineate the broad area described within the treaty. The boundaries are composed of the sum of specific geographies such as lakes, rivers, townships, mountains, administrative boundaries or height of land as mentioned in the treaties transcript. These boundaries are estimated based on written descriptions and should be used for informational and representational purposes only. If there is no geographic description included in the treaty, illustrative polygons may be used to represent locations where the signatory nations, as modern-day collectives, assert and/or exercise Section 35 rights.

The Historic treaties dataset is one of multiple datasets representing treaties and agreements between the Crown and Indigenous peoples. The Crown-Indigenous treaties and agreements geospatial datasets represent the geographic boundaries of the solemn agreements between the Crown and Indigenous peoples that set out promises, obligations and benefits for parties. The following datasets are also available: 1) The Modern treaties (formerly known as the Post-1975 treaties) dataset, which represents the areas of Canada where Indigenous land rights and title have not been addressed by preceding treaties or through other legal means. 2) The Indigenous agreements dataset, which represents established protocols in place for consultation processes, self-government agreements, and other signed agreements between Indigenous groups and the Crown which do not fall into the aforementioned categories. The Historic treaties dataset is Crown-Indigenous Relations and Northern Affairs Canada (CIRNAC) and Indigenous Services Canada (ISC)’s primary source for Historic treaties geographic boundaries on maps. This dataset can also be viewed in the Aboriginal and Treaty Rights Information System (ATRIS). This web-based system provides access to information to inform governments, industry and other interested parties in determining their consultation obligations and in carrying out their consultation research.

Acid-Sensitive Lakes Nine hundred and thirty-three lakes located in Saskatchewan, Alberta and the Northwest Territories were sampled to establish current acidification status. Of the 933 lakes, 244 (or 26%) are considered acid sensitive, almost always because of naturally low calcium and magnesium (or "base cation") concentrations. The most acid-sensitive lakes (i.e., those with extremely low base cation concentrations) are located on the Canadian Shield in both Alberta and Saskatchewan and east of the oils sands development area. Fifty-one of the 244 acid-sensitive lakes were sampled twice annually (spring and fall) to identify chemical changes through trend analyses. Results revealed that 55% of these lakes had concentrations of some metals in excess of Canadian Council of Ministers of the Environment guidelines. Of the 291 samples taken in the 51 lakes, iron concentrations were greater than guidelines in 36% (105 samples), aluminum in 33% (97 samples), lead in 0.3% (1 sample) and copper in 0.3% (1 sample). The metals in these lakes occur naturally and are expected to be found in a wide range of concentrations given the geology and physiography of the Canadian Shield. It remains to establish the relationship between acid sensitivity, geology and high metal concentrations.

This compilation includes S (1251 analyses) and Pb (1622 analyses) isotopic data from nearly 450 mineral occurrences. Approximately 300 of these occurrences are located in Yukon and the remainder are located in British Columbia, Alaska or Northwest Territories. To facilitate data interpretation, a hierarchical deposit model scheme and mineralization age are ascribed to each occurrence. The Pb isotope portion of this compilation builds upon the compilation by Collin Godwin (1988) that was subsequently maintained by the University of British Columbia. Data from Alaska are primarily from the Gaccetta and Church (1989) compilation. This dataset is designed to be used in conjunction with a GIS platform and as such is presented here as a "flat file" (i.e., shapefile, geodatabase and text formats). The simple data structure allows for easier integration into GIS platforms and greater spatial querying of the data. This sulphide isotope database will be subject to periodic updates as new data are acquired through ongoing mapping, exploration and other research activities. Any errors, omissions or new data known to users should be reported to the Yukon Geological Survey. Your feedback contributes to improving the accuracy of the geoscience databases for Yukon.

The inhabited places were chosen according to their dispersion over the territory, their population, their tourist attendance and their location at the ends of numbered roads. The point is located, as the case may be, at the center of economic and commercial activity, at a road intersection, near an important physical landmark such as a church or city hall, or at the center of gravity of a concentration of homes. Names of uninhabited places are included as geographical reference points.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

The health of individual amphibians, amphibian populations, and their wetland habitats are monitored in the oil sands region and at reference locations. Contaminants assessments are done at all sites. Amphibians developing near oil sands activities may be exposed to concentrations of oil sands-related contaminants, through air emissions as well as water contamination. The focus of field investigations is to evaluate the health of wild amphibian populations at varying distances from oil sands operations. Wood frog (Lithobates sylvaticus) populations are being studied in Alberta, Saskatchewan and the Northwest Territories in order to examine the relationship of proximity to oil sands activities and to prevalence of infectious diseases, malformation rates, endocrine and stress responses, genotoxicity, and concentrations of heavy metals, naphthenic acids and polycyclic aromatic hydrocarbons.
