Specifically, this information includes but is not limited to fuel and electricity prices, energy consumption and conservation, and energy supply and demand. This dataset includes supporting information for the Ontario...

Note: This data has been replaced by the Ontario Watershed Boundaries (OWB). We are no longer updating this data. It is best suited for historical research and analysis. A watershed, also known as a catchment basin, includes all land that is drained by a watercourse and its tributaries....

The map shows the annual mean total precipitation. Over much of the continental interior of Canada, precipitation reaches its annual maximum in the summer months and falls as rain. October marks the transition from mainly rain to snowfall across northern Canada.

The map shows the mean total precipitation in the month of July. Throughout much of the continental interior of Canada, precipitation reaches its annual maximum in the summer months and falls as rain. On the Prairies, the maximum monthly precipitation is usually in June or July, but this shifts...

The map shows the mean total precipitation in the month of January. January precipitation across Canada is mainly in the form of snow. Throughout much of the interior and the north, precipitation amounts are generally less than 20 mm and, in the high Arctic, as little as a few millimetres. The...

The map shows the mean total precipitation in the month of April. April is a transitional month across much of southern Canada, when snow is still possible but rainfall begins to dominate the precipitation regime. Precipitation amounts across the southern interior of Canada are somewhat greater...

The map shows the mean total precipitation in the month of October. October marks the transition from mainly rain to snowfall across northern Canada. Snowfall also occurs across much of the interior of southern Canada but in relatively small amounts that usually melt. October also marks the...

This map shows the average maximum snow depth in centimetres computed over 18 winter seasons (1979 to 1997). Over southern Canada this usually occurs in January or February, while the time of maximum accumulation occurs much later in mountain areas and in the Arctic. The main features of the map...

This map shows the median date of snow-cover loss (defined as the last date with 14 consecutive days of snow cover greater than 2 centimetres in depth) computed over 18 winter seasons (1979 to 1997). In areas with permanent or semipermanent snow cover (for example, Arctic ice caps) or in areas...

This map shows the median date of snow-cover onset (defined as the first date with 14 consecutive days of snow cover greater than 2 centimetres in depth) computed over 18 winter seasons (1979 to 1997). In areas with permanent or semipermanent snow cover (for example, Arctic ice caps) or in areas...
