Clunk,

We all know what happens when it's been snowing most of the day, and for those of us who regularly operate in and out of YOW, we are aware of their outstanding runway maintenance!
The CSA may have said Wx delay but in fact, I would hazard a guess it was RSC/RFI that led to the diversion, bit of a technicality, after all the WX is what made the runway slick.
I can't find a copy of the historical NOTAMS for YOW, so I can't say for sure how the runway was.
And it doesn't exactly look like it was ops normal for everyone else.
I'm sure I'd find more if i looked but I truly don't care that much

You said there were 30 minute delays arriving in to YOW, Which wold have put flight 434 OTG at 1747 local, looks like an AC flight landed just before that and then the next AC guy landed at 1951. Maybe they closed the runway for maint?? How much hold fuel do u think they should carry??
Looks like there's more to it than you and your buddy discovered on your blackberrys.
I mean no animosity toward you or your buddy, I have a hard time conveying my tone in type, sorry if it comes off confrontational, that's not my goal.
Merry Christmas and safe flying.
