Chinese-owned TikTok Canada Wednesday filed a federal court challenge to a government shutdown order. Canada ordered the shutdown in November, citing national security concerns.

TikTok has challenged a Canadian government order to shut down the Chinese video-sharing app’s business operations in the country that was imposed over national security concerns.

TikTok's Canadian unit said it has filed an emergency motion with Canada's Federal Court seeking a judicial review of an order that the company shut down its operations in the country on national security concerns.
