Fare Rules
Although you will be seated in the Business Class or Premium Economy cabin when your upgrade is confirmed, your booking will remain subject to the fare rules and restrictions of the booking class you originally purchased. These rules include, but are not limited to, mileage accumulation, change and cancellation fees,
access to airport lounges, and baggage allowance.
Technically, if you are only AC P25K, you do not have access to any lounge, even if you have been upgraded using eUpgrades. Carry a voucher for the MLL just in case.
It looks like the Fare rules were updated, removed "Lounges Access" in limitation, so it is likely that Lounge access is allowed for eUpgrades
Fare rules for confirmed eUpgrades
Although travellers will be seated in a higher cabin when their eUpgrade is confirmed, their reservation will remain subject to the fare rules and restrictions of the booking class and fare option they originally purchased. These rules include, but are not limited to, accumulation of Aeroplan points or Status Qualifying Credit, change and cancellation fees, and baggage allowance.
