Canadian Oil & Gas Prices: WCS, the WTI Differential & AECO
Timestamped Canadian benchmarks — Western Canadian Select at Hardisty, the WCS-WTI differential, and AECO natural gas — with the pipeline context that actually drives them.

Western Canadian Select
WTI Crude
AECO Natural Gas
WTI minus WCS, using each benchmark's latest source record. Check both timestamps above before treating this as a same-session spread.
Each timestamp above is the latest source record for that benchmark, not a page-render time. Benchmarks settle on business days, so a weekend or holiday value reflects the most recent trading session. We do not display synthetic or estimated prices — if a feed is down, the card reads “Unavailable.”
How Canadian Oil & Gas Prices Are Set
Everything prices off egress
Western Canada produces far more oil and gas than it consumes, and nearly all of it starts landlocked in Alberta. The price of every Canadian barrel and molecule embeds the cost of getting it to a refinery or an export terminal — which is why pipeline capacity, not local supply and demand, is the dominant driver of Canadian differentials.
For crude, the WCS-WTI differential widens when Midwest refineries go into turnaround or production outruns pipeline space, and compresses when new egress opens. For gas, the AECO-Henry Hub basis plays the identical role, with NGTL maintenance season standing in for refinery turnarounds.
Two projects changed the map
The Trans Mountain expansion (May 2024) nearly tripled Pacific-coast crude capacity, giving heavy barrels their first large-scale non-US outlet and capping how far the WCS discount can blow out while spare capacity lasts.
LNG Canada at Kitimat did the same for gas: feedgas moving west on Coastal GasLink is structural demand that no longer competes for US-bound pipeline space. Both projects shifted Canadian pricing power at the margin from US Midwest buyers toward Pacific markets.
Refinery demand
US Midwest cokers are the traditional home for Canadian heavy; their turnaround schedule moves the WCS differential directly.
Pipeline balance
Enbridge Mainline apportionment, TMX utilization, and NGTL maintenance set how much supply can physically leave the basin.
Diluent economics
Bitumen needs condensate to flow. Diluent cost feeds straight into WCS blend economics and netbacks.
CAD/USD
Benchmarks quote in US dollars; producer revenue and provincial royalties realize in Canadian dollars.

Canadian Oil Prices FAQ
What is the benchmark price for Canadian oil?
Western Canadian Select (WCS), priced at Hardisty, Alberta, is the benchmark for Canadian heavy crude — the bulk of Canada's production by volume. Lighter Canadian grades price closer to WTI, and synthetic crude from oil sands upgraders trades on its own differential, but when markets quote 'the Canadian oil price' they almost always mean WCS.
What is the WCS-WTI differential and why does it matter?
It is the discount of WCS at Hardisty to WTI at Cushing, covering quality (heavy, sour crude yields less light product) and transportation (the cost of moving landlocked barrels to refineries). It is the single most-watched number in the Canadian oil patch: producer margins, rail economics, and Alberta's provincial budget all key off it.
Why did Canadian oil historically trade so far below US oil?
Pipeline capacity. When Western Canadian production outgrew egress, the marginal barrel had to move by rail — or could not move at all — and the differential blew out beyond US$40 in late 2018, prompting government-mandated production curtailment. The Trans Mountain expansion (in service May 2024) added nearly 600,000 bbl/d of Pacific egress, which has capped that transportation blowout risk while spare capacity lasts.
What is the AECO price?
AECO — formally the NOVA Inventory Transfer point on the NGTL system in Alberta — is the benchmark for Canadian natural gas. It typically trades at a discount to Henry Hub because Western Canada produces more gas than it consumes and the surplus competes for pipeline space. LNG Canada's feedgas demand is the biggest recent change to that balance.
Are these prices in Canadian or US dollars?
US dollars, per North American benchmark convention: WCS and WTI in USD per barrel, AECO in USD per MMBtu. Canadian-dollar realized prices additionally move with the CAD/USD exchange rate; domestic gas trading also quotes AECO in CAD per gigajoule.
Are the prices on this page real-time?
Each card shows the latest record from the OilPriceAPI feed with its source timestamp — the source assessment time, not the page-render time. Crude and gas benchmarks settle on business days, so a weekend view shows the latest trading session. When a feed is down the card reads 'Unavailable' rather than showing a placeholder number.
