OP, was your first segment also booked through ACV? ACV buys seats from AC and therefore has many more restrictions than a mainline ticket since your fare is consolidated with a vacation package. I suspect you will not be able to upgrade your first leg. But you could certainly try when you check-in at the airport. I would not get your hopes up though.
Your second segment to CUN will not be eligible for upgrade, but you will be on rouge so you won't be missing much.
I do not believe this is correct. If an ACV flight is booked in Flex or higher, it should be treated as a normal flight for eUpgrade purposes. AFAIK SE100's and E75's have an additional benefit over other elites where they can upgrade from Tango fares if they booked through ACV.
** For Air Canada Vacations bookings in Tango booking classes, eUpgrades may only be requested on eligible flights between Canada and a Sun destination within the Caribbean, Mexico and Central America. Certain flights departing Cuba may be excluded
OP - confirm if your booking class is Flex for both segments. If it is, you should be good to go.
