About Stamp

This new commemorative stamp honours 150 years of weather observing in Canada. When Lieutenant C.J.B. Riddell had the climate observations operation moved from Old Fort York to a log observatory on King's College, now called the University of Toronto, on September 5, 1840, the first rudimentary, but systematic, recording of the weather began. Today, even though some of the weather observing instruments remain the same, the advent of computer technology and the increasing sophistication of satellites have enabled forecasters to predict the weather with great accuracy. Still many Canadians volunteer their time to record the weather each day. Montreal designer Denis L'Allier and Dominique Trudeau created this stamp by using a photo of clouds taken by David Collins of the Institute for Aerospace Research, National Research Council of Canada.


Designed by Denis L'Allier.
