My friend who is occupying last year's nominee spot until the end of this month has not had much luck - the wait list never clears, so probably very little chance on YYC-YYZ as a E50K.
I'd rather use one of my 2014 nominee spots and see if I can upgrade someone (ideally on a TATL flight) until the end of February. 14 credits left that are expiring end of the month but can also use some of the new ones if you happen to have 2 legs this month.
If you are booked on a flex fare until end of February and your flight has R space, PM me.
