TORONTO -- Facebook and Instagram will charge the goods and services tax on online advertisements purchased through their Canadian operations, but other technology giants said they aren't ready to follow suit just yet.

The U.S.-based social media networks said they decided to apply the taxes by mid-2019 in an effort to "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."

The federal government has long faced pressure to force foreign online services to apply sales taxes to their work, but has shied away from such measures, despite its international trade committee urging Prime Minister Justin Trudeau to make online services pay the taxes so small- and medium-sized businesses don't lose customers to larger firms based abroad.

The decision to charge the taxes could create a windfall for the federal government and bring it closer to the 2020 deadline it set with other G20 countries to develop an international tax plan to address companies that are based in one country but have the potential to pay taxes in another.

In the wake of Facebook and Instagram's announcement, a spokesperson for Twitter Canada said it does not currently charge sales taxes on ads and a representative for Uber Canada said it already applies sales taxes on all of its rides and food delivery orders in the country.

Google referred The Canadian Press to statements the company made back in May indicating that it would comply with legislation, should the federal government create regulations to require the collection of such taxes on digital sales.

The company noted that it already plans to comply with similar legislation Quebec passed around its sales tax.

Meanwhile, streaming service Netflix said only that it "pays all taxes when required by law."

Short-term rental company Airbnb previously asked the federal government for regulation around taxes.

"We think as a platform our hosts should pay taxes. I know people get shocked when we say that, but we do. We think we should be contributing," Alex Dagg, Airbnb's public policy manager in Canada, said in an interview.

"We just need to figure out what are the appropriate rules in place to do that and how can we facilitate that."
