Unlocking the oil sands in the early years

The Sun Company Inc. opened in Canada in 1917 supplying lubricating oils, kerosene and spirits to war plants in the Montreal area.

Meanwhile out west, in a lab at the Alberta Research Council in Edmonton, Dr. Karl Clark worked on the hot water extraction process that separates oil from sand – a process that originated in 1923 and is still used today.
