After the controversial online news bill was passed by parliament, Meta announced it would start to limit news on its platforms to Canadian users.
Large platforms are required by the law to pay news publishers for the content that is posted on their websites.
Some Canadians' access to news has already been tested by Google and Meta.
A similar law resulted in the blocking of Australian users from sharing or viewing news on Facebook in 2021.
The Online News Act of Canada, which was approved by the senate on Thursday, establishes guidelines requiring platforms like Meta and Google to enter into commercial agreements and compensate news organizations for their content.
The law is "fundamentally flawed legislation that ignores the realities of how our platforms work," according to Meta.
It announced on Thursday that news availability for all Canadian users on Facebook and Instagram will end before the bill becomes law.
"A legal framework that requires us to pay for links or content that we do not post and that are not the primary reasons most users access our platforms is neither sustainable nor workable," a Meta representative told Reuters.
The company assured Canadian users that the modifications to news would not have an effect on other services.
The online news bill, according to the federal government, is essential "to enhance fairness in the Canadian digital news market" and to enable financially strained news organizations to "secure fair compensation" for news and links shared on the platforms.
The tests being conducted by the tech platforms are "unacceptable" and a "threat," Canadian Heritage Minister Pablo Rodriguez told Reuters earlier this month.
After discussions with the government resulted in changes, Facebook Australia brought back news content for its users.
Although the government would proceed with the bill's implementation, Mr. Rodriguez's office said on Thursday that he had met with Google and Facebook this week and planned additional discussions.
In a statement, he asked, "If the government can't defend Canadians from tech titans, who will?".
Six months after receiving Royal Assent, which is probably this week, the Online News Act is anticipated to come into force in Canada.
