When I zoom in on the original TIF I see that both wear formation patches, the man on the right may be from the 49th Edmonton Regt but I don't know shoulder titles well enough, while the man on the left has a two-line shoulder title or a Canada tab and a one-line title but too indistinct to determine the unit.
This doesn't explain the Combined Ops badge on his cuff but perhaps one of our other posters can shed light on this.
