Adding airports to flightaware

An airport in the Toronto area that doesn’t have representation on flightaware is Burlington Airpark (CZBA). There are other airports smaller than this one that are listed, and aren’t as busy as CZBA. Brampton CNC3 has it. Any way to add this airport? Any IFR arrivals don’t have complete information, because the arrival time is never noted on flightaware, so flight duration is always “unknown”.

Any admins?? I know there have been similar questions about this, but I’m asking about this airport specifically.
