While I can put in upgrade request for YHZ-YYZ legs for both departure and return, YYZ-ICN legs are showing up as being unavailable--this was not the case when I checked last week. EF shows J4 for departure and J8 for return--R is zero, as usual. My departure is in a couple of weeks and my return about a week after that.
AC makes R space available in ways that are mysterious and unpredictable. So they may open up R space before the gate or they may not. Essentially, if they think they can sell those seats, they probably won't open them for upgrade until they have greater certainty they won't sell them. But the plane won't go out with people on the upgrade list and empty seats in J. So if you submit your request and there are still seats available an hour from departure, you will get upgraded.
