The United States has called Huawei a threat to national security, but the Shenzen, China-based tech company is growing its presence in America’s northern neighbour. In December 2019, the Associated Press reported Huawei will be moving its U.S. research centre to Canada due to sanctions placed on it by the Trump administration. Huawei is a large commercial provider in his country, but officials recognize the threat it poses to Canadian national security, former Canadian Prime Minister Stephen Harper said on "Mornings with Maria" on Friday.
