Now the media is doing it...
From the National Post, quoting Mayor Tory: "that's an issue that is not a municipal issue, per say...".
Where does this come from? It shrieks of barbarism. I assume it is the Post writer's error, and not derived from a printed statement of Tory's.
The expression is per se, literally "through itself", meaning "as such" or "in itself". "Per say" is meaningless.
I have seen individuals make this mistake, and held my tongue. But a newspaper should know better.
ETA: The Globe got it right; the Star and the CBC do not quote that statement in their coverage of the story.
