I am from Toronto. Best thing to do is tour the city center. Shop the Eaton's Centre and don't forget to check out the labyrinth of shops in the underground that spreads throughout the downtown area. To explore it all, you'll need a couple weeks.
Utah is a nice place in spring to see. It's not too hot and the winter chill is gone. After about April or May the temperatures become way too hot.
Ærø is a great island to go see. Many olde structures there; great for photographs. :) Take the ferry there for romance.
