  Toronto's Climate
   
Tales of igloos and sub-zero temperatures might be used to describe other cities in Canada, but not Toronto. Toronto is on the same latitude as Cannes on the sunny Riviera and just slightly — one degree — north of Boston.

In fact, Lake Ontario serves to moderate Toronto's weather to the point that its climate is one of the mildest in Canada. Generally speaking, spring and summer temperatures range from 15 C (60F) to 25C (80F). During winter months, the average daytime temperature, with the exception of January, the coldest month, hovers just slightly below freezing and a snowfall of more than 10 cm (four inches) is unusual.
