Environment Canada says an estimated 12 centimetres of snow fell on the city Tuesday, which elevated the seasonal total past 539 centimetres.
That was the seasonal record set in 1971-72.
Meteorologist Linda Libby says the final, official figures are still being tallied.
She says snowfall records on the Island go back to the early 1800s.
Meanwhile, the city has increased its snow-clearing budget by roughly $400,000 for the coming year and it's already dealing with a $1 million deficit for 2014.
