While the USA has been open about concerns with NAFTA, Canadian political leaders have been largely silent on what they want from the upcoming talks.
The United States on Monday outlined its priorities for renegotiating the NAFTA trade agreement and said it would focus on ensuring better access for USA goods exported to Canada and Mexico in order to reduce the US trade deficit.
