Edson's growth has been based on the rich natural resources in the region.  Initially, the railroad provided access to the Alberta Coal Branch.  In the 1960's, petroleum and related industries added to the prosperity of the Edson district.  In addition, the coal industry was revitalized in the 1970's with the launching of two mines in the area.  The forestry industry has been a major employer in the Edson area since the Town's inception.  Agriculture is also an important mainstay in the surrounding region.  Resources available locally include coal, clay, sand/gravel, oil and natural gas, and timber.
