Resisting AA-Man's sucker-(flame)bait comment re: Tar Sand Nation...

"Strategically located" skylight ?

It's either in the roof or not in the roof. Isn't it ?

When in the roof, and assuming that it's on the equator-facing slope of  
the roof, it's a liability in summer (no means of sun control as with a  
window which can be summer-shaded by appropriately-scaled overhangs) and  
it's a liability in winter (enormous potential for creating ice dams even  
if fitted with a two inch block of styrofoam).

And that's just for starters. "Skylight" is spelled T-R-O-U-B-L-E in  
Canadian. Eh ?
