London and Montreal Time Difference

London runs 5 hours ahead of Montreal. London, United Kingdom keeps Europe/London time (GMT+1), while Montreal, Canada keeps America/Montreal time (EDT). When it is 12:00 midday in London, the clock in Montreal reads about 07:00, which is the single most useful number when you are lining up a call. Both cities can move on and off daylight saving time on different dates, so the gap between London and Montreal is not fixed year-round — the live clocks and difference above are recalculated from atomic time sources, so you are always reading the current offset rather than a value that quietly goes stale twice a year.
