Clock rules in Waterloo

Waterloo keeps EST (UTC−5) in winter and EDT (UTC−4) in summer, the clock of most of Ontario. Not all of Ontario is on it: EST (UTC−5) all year in the areas tzdata describes as “EST - ON (Atikokan), NU (Coral H)” and “EST - Manitoba, ON (northwest)”. tzdata describes Waterloo’s zone, America/Toronto, as “Eastern - ON & QC (most areas)”.

Local mean solar time at 80.52° W is UTC−5:22, so standard time runs 22 min ahead of the sun: it is highest at about 12:22 PM (an hour later in summer). That is 19 min later than in Ottawa, on the same clock.

Waterloo has kept the same clocks as Toronto since at least 1970; the zone’s rules, coming changes and history are on the America/Toronto page.
