Canada on Saturday blocked bulk exports of prescription drugs in response to Trump's efforts to allow imports from Canada to lower some drug prices for Americans.

The Canadian government said it will "continue to be in communication with the White House" over the issue.

U.S. prosecutors say Canada Drugs’ business model is based entirely on illegally importing unapproved and misbranded drugs not just from Canada, but from all over the world.

Canada Drugs was charged with selling counterfeit cancer drugs online over a three-year period ending in 2012.

Investigators say the two packages had been declared as facial masks but contained 26 grams and 24 grams of fentanyl respectively.

The Canadian Border Services alone made about 9,611 drug seizures in the 2015-2016 fiscal year.
