Canada’s weather service – 140 years old and respected worldwide

Since its founding in 1871, our national weather service has grown to be the authoritative source for the weather information upon which most of us rely each day


This past summer, Canada’s weather service – one of the oldest public service institutions in Canada – celebrated its 140th anniversary.

Although systematic weather data had already been recorded by research staff at the Toronto Observatory (located at the University of Toronto) since 1840, our national weather service officially began in 1871. Canada was only five years old at the time, and Sir John A. MacDonald was still our Prime Minister.
