A “secondary agreement” reached in August 1993 on the application of existing domestic labour law, the North American Convention on Labour Cooperation (NAALC) , was severely restricted. With regard to health and safety standards and child labour law, it excluded collective bargaining issues, and its “control teeth” were only accessible at the end of a “long and painful” dispute.  The obligations to enforce existing labour law have also raised questions of democratic practice.  The Canadian anti-NAFTA coalition Pro-Canada Network suggested that guarantees of minimum standards in the absence of “extensive democratic reforms in the [Mexican] courts, unions and government” would be of no use.  However, subsequent evaluations indicated that NAALC`s principles and complaint mechanisms “created a new space for princes to form coalitions and take concrete steps to articulate the challenges of the status quo and promote the interests of workers.”  If the original Trans-Pacific Partnership (TPP) were to enter into force, existing agreements, such as NAFTA, would be reduced to provisions that do not conflict with the TPP or require greater trade liberalization than the TPP.  However, only Canada and Mexico would have the prospect of becoming members of the TPP after U.S. President Donald Trump withdrew the United States from the agreement in January 2017. In May 2017, the remaining 11 members of the TPP, including Canada and Mexico, agreed to pursue a revised version of the trade agreement without U.S. participation.  The North American Labour Cooperation Agreement (NAALC) came into force in January 1994. It is one of two parallel agreements to the North American Free Trade Agreement between the United States, Canada and Mexico.
The agreement is managed by the Commission for Professional Cooperation, composed of a Council of Ministers and a trinational secretariat, based in Washington D.C. Currently, four provinces (Quebec, Alberta, Manitoba and Prince Edward Island) are signatories to NAALC through an intergovernmental agreement. In Canada, the Office for Inter-American Labour Cooperation acts as a Canadian NAO within the Labour Branch of Human Resources and Skills Development Canada. The Canadian NAO also provides for the filing and receipt of public communications (complaints) on labour law issues that arise in the territory of another contracting party and serves as the official auditing body in Canada. President Donald Trump cried as he promised to repeal NAFTA and other trade deals he considered unfair to the United States. On August 27, 2018, he announced a new trade agreement with Mexico, which is expected to replace it.
