If the Trans-Pacific Partnership of Origin (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 former Canada-U.S. free trade treaty was the subject of controversy and controversy in Canada and was presented as a theme in the 1988 Canadian election. In this election, more Canadians voted for the anti-free trade parties (Liberals and New Democrats), but the split of votes between the two parties meant that the pro-free progressive Conservatives (PCs) came out of the polls with the largest number of seats and thus took power. Mulroney and the CPCs had a parliamentary majority and passed the NAFTA bills and bills passed by Canada and the United States in 1987 without any problems. Mulroney was, however, replaced by Kim Campbell as head of the Conservatives and Prime Ministers.
Campbell led the PC party in the 1993 election, where they were decimated by the Liberal Party under Jean Chrétien, who campaigned on a promise to renegotiate or abolish NAFTA. Mr. Chrétien then negotiated two additional agreements with Bush, which undermined the LAC consultation process and worked to “quickly follow” the signature before the end of his term, to give up time and to hand over to new President Bill Clinton the necessary ratification and signature of the transposition law.  A subsidiary 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.”  But for millions of Mexican workers, the signing of the USMCA agreement will have received a shrugging response.
