Sod Houses

Sod houses, or “soddies,” were a common style of dwelling built in the Prairies during the second half of the 19th century. Soddies were small structures cheaply built out of blocks of sod and rudimentary house fittings. Sod refers to grass and the soil beneath it that is held together by the grass’s roots. Although the term “sod house” is primarily associated with Canadian and American structures built during westward expansion, the structures found their architectural roots in Indigenous and Norse practices. Sod houses have come to symbolize the hardship of homestead life, despite shacks and log cabins being the primary form of housing.

Natural Gas in Canada

Natural gas ranks among the fastest-growing energy sources in Canada and is seen by many in the energy industry as a game-changer, a comparatively clean, low-cost and versatile fuel. It can directly generate power and heat and can be chemically altered to produce a wide range of useful commodity chemicals. It burns cleaner and more efficiently than other fossil fuels, releasing significantly fewer harmful pollutants into the atmosphere. Natural gas is colorless, odourless, shapeless, lighter than air and contains a mixture of several hydrocarbon gases, which are organic compounds consisting of some combination of hydrogen and carbon molecules.

The primary consumers of natural gas are the industrial (54.1 per cent), residential (26.6 per cent) and commercial sectors (19.3 per cent). Canada is the fifth largest natural gas producer after the United States, Russia, Iran and Qatar. Currently, all of Canada’s natural gas exports go to the United States through a network of pipelines, making Canada the largest foreign source of US natural gas imports. At the end of 2016, Canada had 76.7 trillion cubic feet of proven natural gas reserves and had produced 152 billion cubic metres of natural gas that year. It is forecasted that global natural gas consumption will double by 2035.

Lac-Mégantic Rail Disaster

In the early morning of 6 July 2013, a runaway train hauling 72 tankers filled with crude oil derailed as it approached the centre of the town of Lac-Mégantic, Quebec. The tanker cars exploded and the oil caught fire, killing 47 people and destroying many buildings and other infrastructure in the town centre. The fourth deadliest railway disaster in Canadian history, the derailment led to changes in rail transport safety rules as well as legal action against the company and employees involved in the incident. Years after the derailment, re-building was still ongoing and many of the town’s residents continued to suffer from post-traumatic stress.

SkyTrain

The SkyTrain is the rapid transit rail system serving Metro Vancouver, British Columbia. It uses mostly Advanced Light Rapid Transit (ALRT) technology, an automated rail system that operates mainly on a raised guideway, although some sections run underground or at street level. Regular service began 3 January 1986. The SkyTrain’s opening coincided with Expo 86, the world’s fair hosted by Vancouver as part of its 100th anniversary celebrations. The system is run by TransLink, the provincial transit agency for the South Coast of British Columbia. It was the world’s first driverless urban rail system. Now, it is one of the longest fully automated rapid transit systems in the world. The SkyTrain has three lines connecting 53 stations in seven municipalities. In 2018, it had more than 495,000 boardings per weekday, on average.

Aluminum in Canada

Aluminum is a lightweight, strong and flexible metal that resists corrosion and is 100 per cent recyclable. It is a common material in vehicles, buildings, consumer goods, packaging, power transmission and electronics. Canada’s aluminum industry began at the turn of the 20th century and grew quickly during both World Wars. Today, Canada is the world’s fourth largest producer and second largest exporter of aluminum. The country nevertheless accounts for less than 5 per cent of global production. Aside from one smelter in Kitimat, British Columbia, all Canadian plants are in the province of Quebec.

Trans Mountain Pipeline Expansion Project

The Trans Mountain Expansion is a project to build about 980 km of new pipe, most of which will run parallel to the existing Trans Mountain oil pipeline. The new line will carry diluted bitumen, or “dilbit,” from Edmonton, Alberta to Burnaby, British Columbia. The expansion will increase the pipeline route’s overall capacity from 300,000 barrels per day to 890,000 barrels per day.

The project’s first owner, Kinder Morgan Canada, sold it to the Government of Canada in 2018. The Trans Mountain Expansion has been a focus of environmental and economic debates, as well as political conflicts. The $12.6 billion project is now under construction.

Keystone XL Pipeline

Keystone XL was a proposed 1,947 km long pipeline project that would have carried crude oil from Alberta to Nebraska. It was owned by Calgary-based TC Energy Corporation. The pipeline was named XL for “export limited.” First proposed in July 2008, it was the prospective fourth phase of TC Energy’s existing Keystone Pipeline system. In Canada, Keystone XL had the support of both the federal and Alberta governments. However, the project faced significant opposition and legal challenges on environmental grounds. In January 2021, United States president Joe Biden cancelled its permit on his first day in office. On 9 June 2021, TC Energy and the Alberta government announced the termination of the Keystone XL pipeline.

Bomarc Missile Crisis

The CIM-10B Bomarc was the world’s first long-range, nuclear capable, ground-to-air anti-aircraft missile. Two squadrons of the missile were purchased and deployed by the Canadian government in 1958. This was part of Canada’s role during the Cold War to defend North America against an attack from the Soviet Union. Prime Minister John Diefenbaker’s refusal to equip the missiles with nuclear warheads led to a souring of Canada’s relationship with the United States, especially once the Cuban Missile Crisis brought the issue to the fore. The issue split Diefenbaker’s Cabinet and contributed to his party losing the 1963 election.

De Havilland Canada DHC-2 Beaver

The de Havilland Canada DHC-2 Beaver, successor to the Noorduyn Norseman, was the all-purpose bush plane of the Canadian North. (See also Bush Flying in Canada.) The Beaver was sturdy, reliable and able to take off and land on short lengths of land, water and snow. It has been called the best bush plane ever built. While de Havilland Canada produced it for only 20 years — from 1947 to 1967 — many Beaver planes still fly today. The Beaver helped connect communities in remote areas of Canada, in addition to serving across the globe.
