A Language Question for the Canadians

[gnomi]

I'm language-posty-girl these days, apparently. I appreciate you all bearing with me.

This one may be a bit odd.

So, I was listening to the interview with David Hewlett that was posted on GateWorld before the beginning of the current Stargate: Atlantis season. And when talking about the first episode of the season, he says that McKay and Ronon are in the Wraith ship, "side by each" in the cocoons. And I scratched my head and said, "Side by each?"

So, here's the question: is "side by each" a standard Canadian phrase (used where I'd say "side by side")? Or is this just part of his idiolect?

Thanks!
