President Trump announced he was ending trade talks with Canada, citing an Ontario government ad that used a clip of Ronald Reagan criticizing tariffs.

The ad, which Reagan’s foundation said misrepresented the speech, prompted Trump to claim the former president supported tariffs and accused Canada of interfering with U.S. courts.

Trump defended tariffs as vital for the U.S. economy and national security, while the ad’s Ontario creators highlighted cooperation against American tariffs, CNN has reported.

The Reagan Foundation clarified the full speech context, noting Reagan’s support for trade and warning that tariffs could harm American workers.
