Wow. A Canadian that uses the word "y'all." As someone who was born in the Southern US (Georgia) and also uses the word "y'all," I'm impressed.
As for what type of room can be used for a darkroom, I would say the bathroom as long as you can block all the light out of it. I would refer you to the "Bathroom and other Temporary/Makeshift Darkrooms" thread but JBrunner beat me to it. Welcome to APUG!
