The agreement has failed to liberalize trade in some areas, particularly the ongoing dispute over coniferous timber. Issues such as trade in minerals, freshwater and conifer wood remain controversial. The exact impact of the agreement is difficult to measure. Trade between Canada and the United States, which had already increased, accelerated after the signing of the agreement.  While exports accounted for about 25% of Canada`s gross domestic product (GDP) over the entire 20th century, exports have accounted for about 40% of GDP since 1990. After the year 2000, they reached almost 50%.  It is impossible to isolate the effects of NAFTA on the broader economy. For example, it is difficult to say with certainty what percentage of the current U.S. trade deficit, which reached a record $65,677 million at the end of 2005, is directly attributable to NAFTA.
It is also difficult to say what percentage of the 3.3 million manufacturing jobs that were lost in the United States between 1998 and 2004 is the result of NAFTA and what percentage would have been created without this trade agreement. It cannot even be said with certainty that the intensification of trade between NAFTA countries is exclusively the result of the trade agreement. Those who support the agreement generally claim NAFTA loans for enhanced trade activity and reject the idea that the agreement has resulted in job losses or a growing trade deficit with Canada and Mexico ($8,039 million and $4,263 million respectively in December 2005). Critics of the agreement generally associate it with these deficits and job losses. Although the agreement existed decades later, it was no longer at the forefront of Canadian politics.  It was replaced in 1994 by the North American Free Trade Agreement (NAFTA). Jean Chrétien`s Liberals were elected in the 1993 election, in part with a promise to renegotiate important parts of NAFTA`s work and environment. In fact, an agreement was reached with Bill Clinton`s Democrats, who created separate secondary agreements to address both concerns. The North American Free Trade Agreement (NAFTA) is a treaty of the United States, Canada and Mexico.
it came into force on 1 January 1994. (Since 1989, there has been free trade between the United States and Canada; NAFTA has extended this regime.) On that day, the three countries became the largest free market in the world – the combined economies of the three nations were $6 trillion and directly affected more than 365 million people. NAFTA was created to remove customs barriers for agriculture, manufacturing and services; Eliminating restrictions on investment protection of intellectual property rights. This should be done while respecting environmental and labour concerns (although many observers point to the fact that the three governments have been negligent in environmental and safety at work since the agreement came into force). Small businesses were among those expected to benefit the most from the removal of trade barriers, as this would reduce trade activity in Mexico and Canada and reduce the administrative burden associated with importing or exporting goods.
