For your own peace of mind, make sure you look up how to spot bed bugs and what to do if you're exposed to them!
I used to be freaked out at the idea, too, especially after hearing some horror stories on the news. But after doing some research, I've learned that they're actually something we can deal with, if we ever pick them up. And hey, on the plus side, they don't spread any kind of disease at all! They're just incredibly annoying.
1. Peel back the fitted sheet and check in the seams of the bed before you sleep in it. You'll see either bugs or little spots. I've been doing this for years and honestly, all I've ever seen is a clean seam.
2. Put your suitcase up on the suitcase rack, and leave your clothes inside. Bedbugs won't crawl up the legs of the rack to infest your clothes.
3. Keep your clothes and belongings off the carpeted floor and bed. Don't let them pile up - keep your belongings tidy.
4. If you ARE exposed, then seal your bags (and all belongings) in plastic and inspect everything carefully before you bring it into your house. Launder everything you can in very hot water. Steam clean the rest.
You don't have to throw your belongings away, especially not if you're Canadian.

A few days out on the back porch (or in an unheated shed) in sub-zero temperatures will kill them all. (Me, I think I'd go for a couple weeks, but YMMV.)
The two things that kill bedbugs are heat and cold.
Be prepared!
