Ontario uses two distinct shapes of signage to mark the King's Highways. Confirmation markers, or reassurance markers, are utilised along the designated road to confirm (near intersections) or reassure (elsewhere) drivers that they are on the correct route. The markers, known eponymously as "shields", feature the route number within an outline in the shape of a shield, topped by a St Edward's Crown. In other cases, particularly when denoting the designation of an intersecting numbered road, a "crown" marker is used, featuring the route number within an outline of the St Edwards Crown. For secondary highways, the route number is within an outline of an isosceles trapezoid, while tertiary roads place the number within an outline of a rectangle. When these markers appear along or at an intersection with the indicated highway, they feature black text on a reflective white background. There are two exceptions to this: The QEW, which features blue text on a reflective yellow background; and toll highways, which feature white text on a reflective blue background.
