CDIA members are Canadian companies that consider the Department of National Defence or foreign defence departments as customers or potential customers. The products and services offered by these companies virtually cover the complete spectrum of products and services in the market place. Some are specialized military equipment or related to specialized military equipment. Many of the products and services are commercial goods and services that are also sold in the commercial marketplace. Many CDIA members produce only commercial products and services some of which they provide to National Defence.
Some members produce both specialized military and commercial products and services.
