The resource industry in Northern Canada was a thriving business. However, access to these forests and mines was by boat and dog sled. Its very remoteness made the creation of these semi-official flights a reality, as the Canadian Government was not prepared to offer air service to these communities.
Whenever a new air service was created, it's inaugural flight was normally the source of great local news.
