The Canadian military could have modern satellite coverage in the Arctic a decade earlier than envisioned if the federal government is willing to follow the example of other countries and embrace commercial options in space, a House of Commons committee heard Monday.

Mike Greenley, chief executive officer of MDA Canada, told committee members Canada has fallen behind the rest of the globe from "a military space capability perspective" and is not effectively working with companies in the aerospace sector.

"As a result, our relevance in a rapidly changing geopolitical world is declining, and along with it, our ability to protect and defend Canadians," said Greenley, whose company is the largest in the country in the space sector, with over $1 billion in sales annually.
