A week or so in Toronto, a city I was excited to visit anyway as I always enjoy being in big North American cities, but which really blew me away. A great blend of modern big-city vibes in the downtown area, combined with a much more laid-back, bohemian feeling in surrounding neighbourhoods.
Besides spending time in Toronto itself, I also took the obligatory day trip down to Niagara Falls. Touristy, but well worth it.
