The service for Vincent will be held at St-Antoine-de-Padoue Church in Longueuil at 11 a.m. It will be closed to the public, but people are invited to gather outside of the church to pay their respects.
Vincent was struck and killed by Martin Couture-Rouleau on Oct. 20 in a St-Jean-sur-Richelieu, Que., parking lot in what CSIS described at the time as a "violent expression of an extremist ideology."
Couture-Rouleau was shot and killed by police following a high-speed chase after he fled the scene.

Cirillo was buried Oct. 28 in Hamilton, Ontario, after a military funeral.
