Total liquids production in Canada averaged 4.26 million b/d in 2014 and is forecast to surpass 6.0 million b/d by 2035. The price crash in 2014 has led to a major slowdown in activity levels and the deferral of most new oil sands projects, and this will depress growth rates during the early 2020s. The main focus of production is Western Canada, which holds the bulk of conventional hydrocarbon resources. It is also home to the world's largest single hydrocarbon deposit, the Athabasca oil sands, which is the key driver of long term production growth. As in the US, technological advancements in horizontal drilling and multi-stage fracture stimulation have enabled operators to exploit tight oil formations, such as the Bakken (Saskatchewan) and Cardium (Alberta), and increase recovery from conventional plays.
