WACCA is an association of residential and commercial contractors who supply and install commercial interior fit-ups, drywall, acoustic ceilings and exterior insulation finishing systems (EIFS).

As members of AAO we participate in the negotiation of the ICI drywall carpenters agreement and especially the monetary terms in the Ottawa area.  We are certified to negotiate residential agreements for board area 15 for the plasterers and the drywall carpenters.

Other areas where WACCA is active with members is in navigating ongoing changes to health and safety policy, identifying new industry trends such as seismic designs, reviewing up-to-date building codes as well as a focus on the Training Centre and Apprenticeship programs.
