Thank you vary much for your feedback.
Yes, sometimes Gander is our first decision for ETOPS planning according to WX minima, as well as CYJT or CYHZ, for example. None of this other airports have the singularity of the "you may expect turbulence during approach" published for CYYT, and though that's not a regulated determining WX condition for ETOPS planning, I think it should be very seriously taken into account. It's not very smart to divert your flight with one engine out to an airport where you'll probably encounter severe turbulence. CRM should start at the office, right?
