Montreal is 1 hour ahead of Lima

Best overlap: 8:00 AM to 5:00 PM in Lima is 9:00 AM to 6:00 PM in Montreal.

Keep meetings inside 8:00 AM to 5:00 PM in Lima — that maps to 9:00 AM to 6:00 PM in Montreal. Despite the 1-hour difference, a 9-hour overlap keeps things simple and gives both teams breathing room. These times hold for most of the year, but Montreal's daylight saving (which Lima doesn't use) shifts them by an hour twice annually.
