Oil Sands

The Canadian oil sands (or tar sands) are a large area of petroleum extraction from bitumen, located primarily along the Athabasca River with its centre of activity close to Fort McMurray in Alberta, approximately 400 km northeast of the provincial capital, Edmonton. Increased global energy demand, high petroleum dependency and geopolitical conflict in key oil producing regions has driven the exploration of unconventional oil sources since the 1970s which, paired with advances in the field of petroleum engineering, has continued to make bitumen extraction economically profitable at a time of rising oil prices. Oil sands are called “unconventional” oil because the extraction process is more difficult than extracting from liquid (“conventional”) oil reserves, causing higher costs of production and increased environmental concerns.

Fracking

​Hydraulic fracturing is a technique used in oil and natural gas production. It releases otherwise irrecoverable resources from certain geological formations by injecting water and additives at high pressure into the ground to create microfractures in the rock. Hydrocarbons can then flow through these fractures into a well. It has become controversial because of concerns that the technique, and well-drilling activity associated with its use, threatens groundwater, surface water, air quality, and other environmental values. Common in Alberta’s oil patch since the 1970s, the practice expanded greatly in this century, triggering gas rushes in British Columbia and Saskatchewan and resistance in several other provinces.

Humboldt Broncos Bus Crash

One of Canada’s most high-profile highway tragedies occurred on 6 April 2018, when a bus carrying 28 members of the Humboldt Broncos junior hockey team collided with a transport truck at a highway intersection near Tisdale, Saskatchewan. The crash killed 16 team members: 10 players and 6 staff. It also led to new truck-driver training and licensing regulations and increased awareness about the availability and use of seat belts among bus passengers.
