But not a "major" impact. The vastly bigger problem where Harbour Air operates is "real" flights (because it's the YVR area) and cargo shipping (because it's also the port of Vancouver).

And for this area specifically, it'd be nice if we stopped having a giant, uncovered piles of sulphur pellets, full of sulphur powder from being dumped in piles, literally getting dispersed every second there's even the faintest amount of wind. Which, given that it's the pacific north west, is "every second of every day".
