Silent Hours Procedure

When an event is taking place outside regular building hours, a Building Services custodian staff member (porter/cleaner) is required to be on site for the entire duration of the event, adding on cleaning fees based upon the square footage of the areas used during the event and 30 minutes (15 minutes prior and after the event) to allow the porter/cleaner to get access to the building assigned and get all keys and material required for the event.

When an event requires the services of a porter/cleaner, Building Services must charge a minimum of 4 hours to call an employee in on overtime. Our rate is at $63.00/hour. The porter/cleaner assigned to the event is to provide exclusive attendant services with a supplied pager number to be reached at all times.

Building Services cannot use its regular weekend employees to open doors for any events held on Campus. A porter/cleaner must be brought in for the purpose of opening buildings and acting as an attendant. The regular weekend employees are, however, available for safety or sanitary emergencies.

All requests are to be submitted by e‑mail and addressed to: special.events [at] mcgill.ca (body: Event%20description%0AEvent%20date%0AEvent%20start%20time%0AEvent%20end%20time%0AEvent%20location%20(Building%20%2F%20rooms%20and%20areas%20booked)%0ANumber%20of%20attendees%0AAlcohol%20served%20(Y%2FN)) . In the email you must identify the following information:

  • Event description
  • Event date
  • Event start time
  • Event end time
  • Event location (Building / rooms and areas booked)
  • Number of attendees
  • Alcohol served (Y/N)
