Have any airports in Canada announced intentions to open OSS-compliant "sterile" transfer areas? Which airports in Europe have them in terminals to which AC flies?

I often connect both when travelling to Europe (i.e. connect in an AC European city to my final destination) and on the return to Canada (i.e. connect in YUL or YYZ to get to YOW). I would select my connection point based on whether or not I needed to reclear security, when there is no other disadvantage to an OSS airport over a non-OSS airport.

Perhaps as this information becomes known we could have a Wiki with the list of airports providing/intending to provide OSS-compliant transfers.
