Well since the last post offering a crashspace in Toronto was technically made in 2005 and I'm not sure the author is even active anymore, I figure I'll throw this out there.
I can't offer much in the way of luxury of course, I just have a small bachelor apartment and all - but I've got extra blankets and such, so if you're not adverse to spending a night on the floor, then you're more than welcome. Beats sleeping at the bus station or something, most likely.
I'm just off a subway station near the downtown, and I don't own anything worth stealing...so it's perfect!
