I would like to understand what blends of oil are used to supply the Canadian market.

Is there a percentage of West Texas and Brent Crude used along with Canadian produced product?

Is there a percentage oil produced from Canada's oil sands that finds it way into the crude oil stream used for production of auto grade gasoline?

How does the various blends effect the cost at the pump.


Hi John,
Thanks for your questions. Regarding the blends of oil in Canada, it really depends on each supplier and refinery. We can only comment on our refineries here in Canada.

For example, our refinery located in Edmonton, Alberta uses 100% synthetic crude derived from Canada’s oil sands; our Sarnia refinery is a mix of synthetic and conventional crude and Montreal uses only conventional crude. There was a recent blog post on the Globe and Mail site that talked about the relationship between oil prices and gasoline prices that you might find interesting. I have linked to that discussion here:


The bottom line is that retail prices are a function of a number of factors which include crude oil feedstocks, the wholesale price for gasoline and local market dynamics.

Hope this helps.
