From 1955 to 1957 HMCS Labrador was the Canadian government’s most visible presence in the Arctic. Commissioned at a time when the region was at the forefront of continental defence, the naval icebreaker worked with American partners to establish defence facilities, survey shipping routes, and show the flag in an area of growing strategic importance. A critical and often unsung element in Labrador’s success was the embarked helicopters. By spotting leads, moving people and cargo, and surveying routes, these aircraft enhanced the ship’s effectiveness, range, and impact. This volume is a collection of those flight logs. It provides a documentary snapshot of early icebreaking and helicopter operations in the Far North and provides researchers with new tools to study Arctic defence and navigation at a critical juncture of the early Cold War.
