Depending on where you live there, it would come in handy, lol. Also, you won't really experience winter like Toronto had, but you can visit snow almost any time you feel like it. Just look east, and up.
Meetup in Seattle? Wear rubber boots and carry a broom to sweep the used needles out of your path. Bring rubber gloves, too, you can't sweep everything. I hope you don't mind the smell of marijuana and meth smoke. My city is gone.
Welcome to the Pacific Time Zone. Vancouver BC in the winter? Christmas will be fun... then your going to freeze your Back Bacon.
Pacific North West is clean and green and you get to see some real mountains.
sweet tea is not iced tea in the rest of the country, but in most of the southeastern USA, it is. (not sure on Florida)
You ask for iced tea in some parts of the country and it's sweetened. In other parts, it's unsweetened. In some places, you ask for sweet tea, you get unsweetened and some sweetener plopped down next to it, in still others, if you ask for tea, you get flavored tea, not black tea (sweetened or unsweetened). Finally, if you ask for iced tea in some places, they give you a glass of ice, and a pot of hot water and a teabag...
As for where you and your family are from...welcome to North America. Most of us are mutts, and dang proud of it. My family is part German, part French, and part English/Irish/Scottish. My wife is English/Italian. My sister-in-law is Puerto Rican, my Uncle is a Native American. It's who you are that matters...not what you are.
Lastly, Congrats on the move. I've been to Toronto, but I liked Barrie more (less people). However, I love Vancouver. It's an absolutely gorgeous city. That said, I think Victoria is even better....but i've only seen that city from a vacationer's perspective, while I was in Vancouver for both vacation on time, and business several, other times.
