Essentially, Shaikh was more of an active participant and instigator in criminal activities than a fly-on-the-wall informant, Chernovksy said after the verdict.
Shaikh defended his role.
"Stopping something from happening or even protecting the honour of the Muslims, protecting the honour, the integrity of our country . . . I would do it again a thousand times.''
In his ruling, Sproat rejected defence arguments that two camps organized by the alleged ringleaders were simply a religious retreat or recreational in nature.
Sproat noted participants, including the accused, marched, played paintball games, shot a 9-mm handgun, and heard lectures on waging war on the West during a camp north of Toronto in December 2005.
"It is inconceivable to me that by the end of the camp there was any doubt about its purpose,'' the judge said.
