The original NFB caption:

The men who man Canada's radar stations are tough; each day they pit their strength, their wits, their intelligence and their endurance against savage weather conditions, where the temperature drops mercilessly to 60 degrees below zero, and against the inevitable loneliness which accompanies the desolate isolation of these vital outposts. Only a few crack, the majority grow tall.

Notes:

The image appears to be a Mid-Canada Line (MCL) station, although there is a small possibility this is a AN/FPS-23 radar of the DEW line (FPS-23 generally used rectangular antennas, not round as in this image). The large tower on the left is the radar mast, which in this case has antennas facing only one direction, whereas most would have a second set pointed towards the next tower in the chain. The large parabolic antennas in the middle of the image are part of the tropospheric-scatter radio system that sends data to NORAD.
