Quiet spots for virtual meetings at night

I am here in Montreal for a few weeks to visit with in-laws. As it happens, I have some important Zoom meetings coming up (one of which is a job interview) during Asia-morning hours, i.e. ~9pm - 11pm local time.

I don't want to do these from my relatives' home and wonder what options exist. Looked into neighborhood libraries, but they are closed at night, and in any case, I wouldn't have access to a private room.

I thought of a hotel lounge somewhere, but might end up with dim lighting and lounge music (or no/lousy wifi).

Any suggestions? I am staying near the Concordia Loyola Campus, but have access to a car.
