Your website says (open 10:00 AM to 6:00 PM) so I arrived Thursday June 7 at 10:15 AM and it was locked up - no notice of why it was closed, or when it would be open. The security person in the main lobby said she didn't know why it wasn't open, so I decided I would walk to the AGO and come back after that. I visited the AGO, had lunch and went back to the Aird Gallery only to find it still closed at 12:20PM. still no note or explanation. Hard enough to get people out to galleries without this.
