That goes back to the point that we try to keep different types of operations systematically separated. If you look at parachute operations, they're flying using something called VFR navigation, so the pilot is responsible for their manner of operation. As a pilot, they're not on a specific route.
Then, if you look at approaching Montreal, they're on IFR routes. They're on a set of very specific, published routes. It's always safer for us to keep those types of operations away from each other.
