"The Americans and the Brits are watching this case closely as well, as a sign to see whether Canada takes terrorism very seriously," CBC's Rosemary Barton reported from the Ottawa courthouse.
Police raided Khawaja's family home in the capital in March 2004 as part of a British and Canadian investigation.
Five British men charged in the case were convicted last year and sentenced to life in prison.
Khawaja, a computer software developer who was working for Canada's Foreign Affairs Department, has spent the past four years in jail.
He is accused of building remote-control triggering devices for a bomb-making cell east of London plotting to attack nightclubs and shopping centres.
