The oil sands
Alberta's oil sands — the resource that makes Canada a top-4 producer
What the oil sands are:
Bitumen is oil so viscous it cannot flow through a pipeline without processing — mixed with sand and water underground across 141,000 km² of boreal forest in northern Alberta (Athabasca, Cold Lake, and Peace River deposits). Shallow deposits are surface-mined; deeper ones use in-situ steam injection (SAGD) to heat the bitumen until it flows. Both methods are far more capital- and energy-intensive than conventional drilling, and produce more emissions per barrel — a major reason Canadian oil has become politically contentious both domestically and among trading partners. Approximately 94% of Canada's proven reserves (roughly 165-169 billion barrels total) are oil-sands bitumen, giving Canada the world's third or fourth-largest reserve base, behind Venezuela and Saudi Arabia.

Getting it to market:
Nearly 95% of Alberta's diluted bitumen is exported to the United States, since Canada's own refineries lack the residue-conversion capacity to process it domestically. Pipelines carry approximately 88% of crude oil out of Western Canada. The Trans Mountain Expansion (TMX) — Canada's only pipeline to the Pacific coast — entered service in May 2024, roughly tripling capacity from 300,000 to 890,000 bbl/day and finally giving Alberta oil a route to Asian markets that doesn't run through the US. The earlier Keystone XL pipeline, which would have carried oil sands crude to US Gulf Coast refineries, was repeatedly approved and cancelled across successive US administrations before being scrapped in 2021 — one of the most politically contentious energy infrastructure fights in North American history.

Hydro and nuclear — the clean grid
How Canada built one of the world's cleanest large electricity grids
Hydropower — the backbone:
Roughly 60% of Canadian electricity comes from hydro, making Canada the world's third or fourth-largest hydroelectricity producer. Some provinces run almost entirely on it: Manitoba (~99.5%), Quebec (~97%), Newfoundland and Labrador (~97%), and British Columbia (~89%). Quebec's Robert-Bourassa station (5,616 MW), part of the vast James Bay hydroelectric project, and Newfoundland's Churchill Falls (5,428 MW) rank among the largest hydro plants on Earth. Most of the largest reservoir dams were built before 1990; newer projects tend to be smaller run-of-river developments.

Nuclear — concentrated but massive:
Nuclear supplies approximately 13-15% of Canadian electricity, almost entirely from Ontario, using Canada's own CANDU reactor design — heavy-water moderated reactors that run on natural, unenriched uranium, distinguishing them from the enriched-uranium light-water reactors used almost everywhere else. Bruce Nuclear Generating Station, with eight CANDU units at roughly 6,400 MW combined, is the world's largest operating nuclear power station by reactor count, supplying nearly 30% of Ontario's electricity. Ontario also completed a full coal-power phase-out in 2014 — the first jurisdiction in North America to eliminate coal generation entirely — replaced mainly by refurbished nuclear capacity and natural gas. CANDU technology has also been exported to South Korea, Romania, China, and India.

Questions
Questions about Canadian energy
Why does Canada produce so much oil but rank so low in most people's mental map of major oil producers?
Canada's oil is unusually invisible in global energy conversations for a producer of its size, and the reason is structural. Unlike Saudi Arabia or Russia, where a single state oil company controls a strategic, easily narrated resource, almost all of Canada's oil comes from Alberta's oil sands — bitumen mixed with sand that must be mined or steamed out of the ground rather than pumped from a well, then diluted or upgraded before it can even enter a pipeline. That makes it capital-intensive, slow-growing, and industrially unglamorous compared to a Gulf oil field. Nearly all of it — around 95% of Alberta's diluted bitumen — flows south into the United States rather than onto the global tanker market, so it rarely shows up in the same conversations as Saudi or Russian exports, which are sold worldwide and command daily headlines. Canada also lacks a single dominant national oil company the way OPEC members do; production is split across many private operators (Suncor, Canadian Natural Resources, Cenovus, and others). The result: Canada is the fourth-largest producer and the single largest supplier of crude to the world's largest economy, yet it's rarely mentioned in the same breath as the traditional oil powers.
