[2] Armstrong is a rural community and commercial center in the North Okanagan, with agriculture, grain farming of alfalfa and corn,[1] logging, and ranching being traditional economic activities.

The influence of Dutch immigrants settling in the valley after the Second World War is represented by their cheese-making knowledge, allowing Armstrong to become well known for the cheese it produced.

The "IPE" is not just a midway and popular retail show, but very much still a country fair, with contests being held to judge animals, cooking, sewing, hobbies, and other items.

Armstrong is a corporation operated by a seven-member city council headed by the Mayor, with meetings being held the second and fourth Mondays of every month.

[4] While agriculture, logging, and ranching remain a dominant portion of the economy of Armstrong and the Spallumcheen Valley, tourism increasingly plays a significant role in the economic activity of the area; particularly popular with long-distance cyclists as a desirable location for short-haul excursions.

Saputo Inc. purchased Dairyworld in 2003, and in February 2004, after being in operation for more than 100 years, closed the Armstrong Cheese site down, laying off 73 workers.
