If you are brave enough to cross the border, Ontario in the fall is spectacular. Late September to late October is my favourite time of year. Toronto is a wonderful and multicultural city (in spite of the mayor), and there are so many things to do. Head to the Niagara area to wine tours, then to the Kitchener area (where I now live, after moving from Toronto last year) for Octoberfest. Check it out online- so much- theaters, restaurants, shopping, and the US dollar is in your favor now.
