Autumn hits a sweet spot in so many ways in Toronto and other Eastern Canada destinations, like Ottawa and Montreal. There's a crispness to the air that warns winter is around the corner. This change in temperature gives vigor to the city, possibly reminding its people that they better make the most of the weather before it's freezing cold.

Aside from Thanksgiving, which Canadians observe a month earlier than their American buddies to the south, October is mostly a month in which Torontonians continue to enjoy the outdoors by hiking, biking, sitting on patios, and boating. Those with cottages will probably close them up for the season.

Halloween is celebrated on October 31st, but it is a work and school day as usual.
