Pearson is hosting a public meeting November 7, where you can ask questions about operations overhead, and ask about changes that has impacted your neighbourhood. 

Here's the link to attend: https://www.eventbrite.ca/e/pearson-public-meeting-in-person-attendance-tickets-1043956350547?aff=erelexpmlt

You can attend virtually, but it's way better to attend in person, as you have more opportunities to ask question as well as talk to NAV Canada officials before/after the meeting.
