I would say its the VA end.
VA is not happy to join *A, or maybe they can't afford to pay the ongoing fees.
If you take an indepth look, it would probably cost a lot of money to fully intergrate into an alliance, FF wise, not only between VA and AC, but between VA and the rest as well.
Not only in your case, don't know what class you were booked into, and if your class of travel is an eligible class of earn in VFF.
One member on another thread, mentioned they couldn't find an eligible class of earn in VFF for flying ACd, a few threads below this one of yours.
Tho, according to the pointshack, VFF WP should get lounge access, but don't think that there is a Mapleleaf lounge in SYD, so you would probably have accsss on the way back from Canada to Aust.
Hopefully, you still have the paperwork, ie, the PNR etix, so that you can claim if the points don't appear in your VFF account.
It was mentioned on another past thread,
that no SC are earnt flying AC, but this might have changed in the meantime since the AC and VFF agreement went "forward".
Edit: can earn VFF SC on AC flights now, so long as its in an eligible class.
Anyway, hope you do get all the points you counted on getting.
On an aside, the CBSA officers from what I see on youtude scare me, and as mentioned, I have no need to go up there to Canada to see snow, NZ will do me very well.
