I'm flying YYZ-AMS on 9W in J next week.

When I booked, I was under the impression 9W flew out of Terminal 1 and used the AC Maple Leaf Lounge. Now it seems they are operating out of Terminal 3. That's a bit annoying as I'm arriving at Terminal 1 on a separate ticket earlier in the day, but AC can interline the bags so 2:42 should be enough time to connect.

Can someone tell me which lounge 9W's J passengers are using at Terminal 3 and if it has a shower? I want to freshen up if possible before the overnight flight to AMS.
