    Toronto enjoys a wonderful location by Lake Ontario, in Ontario province in the far south of Canada. It’s very close to the border with America. The mild temperature of the water in October stops the air temperature falling too low in early autumn and you don’t need to worry about snowfall yet. Seeing the leaves change colour around the lake is quite stunning.


    The weather in Toronto in October has a daytime average high temperature of 16°C, which compares very well with Canadian resorts further north and around the mountains. It could fall to 10°C on colder days with occasional frost. The night time temperature is likely to be around 5°C to 7°C on average. Bring your sunglasses for your trip to Toronto in October, because you’ll have around six hours of sunshine from 11 hours of daylight. It won’t be particularly wet this month with only 48mm, on average, for the month across just nine rain-affected days. The heat and UV levels are low to moderate and the humidity mark is likely to be around 78% in Toronto in October.
