I'm nitpicking, but unless I'm misunderstanding you, what you're saying about Southern Ontario having weather like DC in July is a little off. Average high July DC is 88F. Average high July Detroit (close to S Ont) is 83F. It's similar, but 5F is definitely a difference. Sharing the facts because I find this stuff interesting! Opinion: DC often feels hotter than it actually is due to the high humidity, which gets worse the farther down the east coast you go. I've never been to Southern Ontario in July though.
