Strathcona refinery: 70 years and counting

From the discovery of oil at Leduc No. 1 in 1947 to “oil-in” day at Strathcona on July 17, 1948, Imperial has a long, rich history in the Edmonton area. The Strathcona refinery has come a long way from the early days of a small 6,000 barrels a day operation to one of the most safe, reliable and profitable refineries in North America today. Here’s a look at the Strathcona journey:
