OTTAWA – Social media giants Facebook and Instagram will soon be charging sales tax on online advertisements on their platforms that are purchased through their office in Canada.

CTV News has confirmed that, by mid-2019, both services will be charging the goods and services tax, which could result in a considerable tax revenue for the federal government.

Last year, Facebook, which owns Instagram, announced that it would be moving to a “local selling structure” in countries where they have offices to support local ad sales.

"This means that advertising revenue supported by our local teams will no longer be recorded by our international headquarters in Dublin, but will instead be recorded by our local company in that country," Facebook Chief Financial Officer Dave Wehner said at the time.

"We believe that moving to a local selling structure will provide more transparency to governments and policy makers around the world who have called for greater visibility over the revenue associated with locally supported sales in their countries," Wehner said.

As first reported by The Logic, this move sets the two services apart from other foreign-based tech platforms.

In a statement to CTV News, a spokesperson for Finance Minister Bill Morneau said that the government is working with digital providers to attract investment and is seeking clarity from Facebook and Instagram to “determine the way forward.”

Spokesperson Pierre-Olivier Herbert said that the minister is "committed to ensuring that Canada's tax system is fair and supports an innovative economy."
