1958 - Rapid Technological Growth

The 1950s and 1960s were a period of rapid technological growth in Canada. Aerial photography and mapping improved significantly during this time period, and geoscientists made increasing use of helicopters, replacing the use of pack horses and canoes.

It is estimated that between 1952 and 1958, the Geological Survey of Canada was able to map about 50% of Canada at a reconnaissance scale – a significant achievement over previous efforts, which had taken 110 years to be completed.
