Pearson Airport in Mississauga is still digging out today from Monday’s massive winter storm that dumped one of the highest snowfall totals ever reported in a single snowfall event at the airport.


The 33cm of snow measured at Pearson fell within the top 10 highest reported snowfall totals at the Mississauga-based airport, according to a summary from the Ontario Storm Prediction Centre.

Pearson normally averages about 40cm of snow in an entire month.

At times on Monday, the snow was reportedly falling at Pearson at a rate of more than 10cm an hour.

Weather officials say the last time Pearson recorded more than 30cm in a single storm was in 2008.

The largest single-day snowfall recorded at Pearson Airport was 45.5cm in February 1965, according to the summary, which also noted that the 45cm recorded yesterday at Ottawa International Airport is a top 10 event there as well.

Yesterday’s massive snow dump in Mississauga and across the Golden Horseshoe was described by Environment Canada as a “once-in-a-decade kind of storm.”

Environment Canada severe weather meteorologist Ray Houle told CBC News that, “the general consensus around here is that it was a pretty historic storm. Not very often do we get a storm that brings snowfall amounts and blizzard-like conditions like that to the Golden Horseshoe and the GTA.”

Some parts of Mississauga reportedly received as much as 45cm of snow on Monday.

UPDATE: Pearson Airport officials said on Wednesday (Jan. 19) that Monday’s snowfall (33cm) was the third-largest single-storm snowfall amount recorded at the airport since 1937.
