1. The Canadian Arctic and the Cold War
Alert is the most northerly, permanently inhabited location in the world, located only 817 kilometres from the geographic North Pole. The station was first settled in the early 1950s as a weather station of the Joint Arctic Weather Station (JAWS) System.
On Sept. 1, 1958, Alert began its operational role as a signals intelligence unit of the Canadian Forces. At that time, it became the Alert Wireless Station and was under the command of the Canadian Army. During the Cold War, Alert was strategically important because of its proximity to the Soviet Union. Alert was the closest point in North America to the northwestern area of the Soviet Union. At its peak, CFS Alert had upwards of 215 personnel posted at any one time. The station became a key asset in global intelligence sharing , with Alert being privy to many secret Soviet communications regarding land-based and sea-based ICBM test launches and many operational military deployments.
Upon the unification of the Canadian military forces, the Alert Wireless Station changed its name to Canadian Forces Station Alert (CFS) on February 1, 1968
The cover below was sent by a member of the armed forces from CFS Alert in 1968:

2. Arctic Navigation
Canadian Coast Guard icebreakers assisted maritime traffic move safely and quickly through, or around, ice-covered Canadian waters.
i) CCGS Sir Humphrey Gilbert
The Canadian Coast Guard Ship CCGS Sir Humphrey Gilbert was an icebreaker built in 1959 by Davie Shipbuilding. Ltd., Lauzon, P.Q. The ship was then assigned to the Newfoundland Region to provide servicing of fixed and floating aids to navigation, ice breaker support, and search and rescue in both Newfoundland and Arctic waters. CCGS Sir Humphrey Gilbert was retired in 2001 She was sold to private interests and has been given the name Polar Prince.

CCGS D'Iberville was in service from 1953- 1983.

b) SS Manhattan Voyages : Canadian Sovereignty over Arctic Waters
The SS Manhattan was an oil tanker owned by the Humble Oil and Refining Company. It was the largest ship in the U.S. merchant fleet and after being converted to an icebreaker it was used to navigate a route through the Northwest Passage in an attempt to determine whether it would be commercially feasible to transport oil from Prudhoe Bay, Alaska.
i) Northwest Passage Voyage 1969
The Canadian government was not asked permission for the SS Manhattan's voyage. This raised a political problem for the government because Canada considered the waters of the Canadian Arctic Archipelago to be internal waters. Canada nevertheless gave unsolicited permission and provided the Canadian icebreaker CCGS John A. Macdonald to escort the vessel.
The SS Manhattan became the first commercial ship to cross the Northwest Passage. The Manhattan crossed the passage from east to west, entering the Arctic's Parry Channel on September 2 1969. One single token barrel of crude oil was loaded at Prudhoe Bay on September 20, 1969, and the ship returned east the next day, arriving in Halifax in November.
The card reads:
"Artist's conception of S.S. Manhattan's maiden voyage to open commercially the Northwest Passage."

Mailed at Resolute, NWT, October 28 1969
The Manhattan was escorted by the Canadian icebreaker CCGS John A. Macdonald and the U.S. Coast Guard icebreaker CGC Staten Island.
Handstamps from both icebreakers were applied to this cover, also mailed from Resolute on the eastbound trip, October 28 1969:
ii) SS Manhattan Second Voyage : 1970
A second voyage by the SS Manhattan in April 1970 prompted Secretary of State for External Affairs Mitchell Sharp to inform the House of Commons that Canada had agreed to permit a second voyage of the SS Manhattan. In 1973 the Canadian Government claimed that the waters of the Canadian Arctic Archipelago were internal waters on a historical basis.
In her second voyage, the SS Manhattan spent several months researching navigation through Arctic ice.

3. Arctic Research
a) Tanquary Fiord Defence Research Board (DRB) Camp
Operation Tanquary was initiated by the DRB in 1962 with the establishment of a research base camp at Tanquary fiord. From thid base, the DRB coordinated a wide-ranging program of scientific research, for which studies were undertaken over much of northern Ellesmere Island. Much of the program focussed on sea ice research, but also included studies in meteorology, oceanography, glaciology, biology, and archeology. Operation Tanquary concluded in 1972.
Harold Serson (1926-1992) was a technical officer for the DRB who established a reputation in remote arctic science operations and logistics.
Mailed out from Tanquary Fiord and cancelled at Resolute on May 14, 1970
Names of researchers H. Serson M. Springate printed on the envelope. The letter was flown out by "D/H Otter RWV Pilot J. Lafrance"

b) Hudson Project 1970
The CSS Hudson (now CCGS Hudson) was built in the early 1960s for the Canadian Oceonographic service. She was the largest vessel built at that time specifically designed for research purposes. On November 19, 1969 the Hudson began an 11 month, 58,000 mile cruise, known as "Hudson 70", the first ever to circumnavigate North and South America. More than 122 scientists from many countries obtained valuable chemical data in the Atlantic, physical data in the Chilean fjords, gravity data in the Pacific and geophysical data in the Arctic.
By late August 1970, the Hudson entered the Beaufort Sea where scientists studied the geology of the seafloor. Hudson completed the circumnavigation in October 16, 1970.
