How do I seal holes in the vapor barrier around electrical wires?

So I'm going to insulate part of my 3rd floor/attic. I'm putting in pot lights and some of the outlets will be on outside walls and all those have to be in side the vapor barrier. (I'm ripping out the existing plater and lathe and drywalling it, so I figured I might as well fix the electrical stuff while I'm in there)
So I assume I have to poke a hole in the vapor barrier to get the electrical wire through, but then what? Do I just leave a hole in the barrier? Or do I have to seal it with something? Google is no help. This is in Ontario if it makes a difference from a code point-of-view.
