In the broadest sense of the word, energy is a substance’s capacity to do work or produce an effect, such as burning coal to create heat. Canada is home to vast quantities of both renewable (e.g. wind) and non-renewable energy sources (e.g. oil). This collection gathers all of The Canadian Encyclopedia’s articles relating to energy, from various types to the means by which they are sourced.
Pipelines are systems of connected pipes used to transport liquids and gases — namely oil and natural gas — across long distances from source to market. More than 840,000 km of pipelines criss-cross the country, part of a larger oil and gas sector that employs between 100,000 and 200,000 Canadians. According to Natural Resources Canada, the sector earns the government an average of $19 billion in royalties, fees and taxes each year. It also contributes nearly 8 per cent of Canada’s gross domestic product. Yet pipelines have also been controversial in Canada over fears that the fossil fuel use they facilitate could be significantly contributing to climate change. In recent years, Indigenous groups, environmentalists, municipalities, mayors and labour unions have opposed numerous pipeline projects they believe could contaminate local waterways through spills and leaks.
In 1970, the Canadian government introduced guidelines for the development of a pipeline corridor south from the Mackenzie River delta to Alberta and the United States. Energy companies have since proposed three separate projects to transport natural gas by pipeline along this route — the Arctic Gas Pipeline, the Foothills Pipeline and the Mackenzie Gas Project — with an oil pipeline likely to follow in the first two cases. However, due to high costs, engineering challenges, environmental concerns, Indigenous land claims and changing markets, none of these pipelines has been built.
SchoolNet was an educational project launched in 1993 by federal, provincial and territorial governments, educational organizations and industry partners. Their goals were to link Canadian schools and libraries (particularly those in remote areas) via the Internet and to foster the creation of a Canadian educational website in English and French.
Floods are primarily caused by naturally occurring changes in the height of rivers, lakes and oceans. According to Public Safety Canada, floods are the most common natural hazard in the country and among the costliest. Historic floods have occurred across Canada, with many of the worst happening on major river systems that pass through populated areas. Scientists predict that flooding linked to the impacts of climate change will increase as the 21st century progresses, particularly in coastal areas of the country.
Canada is the world’s leading producer and exporter of maple products, accounting for 71 per cent of the global market. In 2016, Canadian producers exported 45 million kg of maple products, with a value of $381 million. The province of Québec is by far the largest producer, representing 92 per cent of Canadian production. Maple syrup and maple sugar products are made by boiling down the sap of maple trees. World production of maple syrup and sugar is mainly limited to the Maple Belt, the hardwood forest stretching from the midwestern United States through Ontario, Québec and New England and into New Brunswick, Nova Scotia and Prince Edward Island; however, British Columbia, Manitoba and Saskatchewan also produce some syrup.
