From the Canadian Encyclopedia website: A review by the Saskatchewan government of the crossroads where the crash occurred found that the frequency of collisions there is low compared with other intersections in Saskatchewan. Even so, the intersection was the scene of another deadly crash in 1997, when six family members were killed after their pickup truck sped through the crossroads without stopping, colliding with a tractor-trailer.

2 deadly accidents in 20 years. The number of casualties is high but if there were 2 casualties, would it be considered a dangerous intersection that needed all the additional safety features added?

Long straight and flat with an oversized sign and flashing light.

Uh no it wasn't. In the direction the truck was going, you could see the stop sign 3 miles before the intersection. Trees on the south east corner only had a negative effect if you weren't going to stop. At the stop sign there was clear visibility in all directions.
