On November 6, 2001, Bill 11 (the Architects Act) received assent in the Northwest Territories Legislative Assembly, creating the Northwest Territories Association of Architects (NWTAA).

With the NWT Architects Act, the NWT Architectural Society, which had acted in the general interest of architects in practice in the NWT since 1986, was transformed into a fully self-regulating professional association.

On November 23, 2001, NWTAA became the 11th signatory to the Canadian Architectural Agreement, allowing for reciprocity between the provinces and the NWT, and set standards for education, experience and examination for NWTAA members.

To celebrate the creation of the new Association, a gala was held at the Legislative Assembly in Yellowknife on November 24, 2001 with representatives from the 10 provincial associations, the Royal Architectural Institute of Canada (RAIC), the Canadian Architectural Certification Board (CACB), the Canadian Council of University Schools of Architecture (CCUSA) and the National Council of Architectural Registration Boards (NCARB) in attendance.

As of April 1, 2002, only a member, licensee or permit holder of the Association is entitled to practice or offer to practice architecture in the Northwest Territories.

The NWTAA is a full member of the Canadian Architectural Licensing Authorities (CALA) and sustains full reciprocity with all other Canadian jurisdictions.
