The search for oil

Original Toronto Star caption: The search for oil: Dave Stewart is the engineer in charge of a helicopter landing pad being built aboard this ship; the Beaver MacKenzie; as it sits ice-bound in Tuktoyaktuk harbor. The ship was leased by Imperial Oil Ltd. to help in its Arctic exploration program--a multi-million-dollar gamble which is aimed at finding new reserves of energy to heat Canadians' homes; fuel their cars; trucks and boats and power their factories.
