Since the big rigs entrenched in the core of Canada’s capital first pulled in nearly three weeks ago, they have arranged themselves in a semblance of order, parking in evenly spaced rows. Their drivers have stayed warm and are fed by a corps of marshaled volunteers. And though they have varying personal beliefs, they appear carefully on message: "Freedom!” has been the repeated refrain for the past 19 days.

It is no accident: High above the clot of trucks on Ottawa’s Parliament Hill, in hotel rooms just out of the fray, are the war rooms behind the operation. From them, a team of self-appointed leaders — some with military and right-wing organizing backgrounds — have orchestrated a disciplined and highly coordinated occupation.

They have spent the weeks huddling in conference rooms and streaming their own news conferences on social media platforms from hotel lobbies. It is a crew that includes former law enforcement officers, military veterans and conservative organizers, a sometimes fractious collaboration that has nonetheless helped to coalesce a demonstration against vaccine mandates into a force that has destabilized the city and sent shock waves throughout Canada.
