It may be cold, but Toronto is not Chicago.
I'm sitting here watching The Dresden Files with MizBubs for the first time, and I noticed that it's set in Chicago. But even before I saw all the pine trees in what was supposed to be "Jackson Park" I knew it was yet another "Chicago" feature shot in Toronto. How? Because the voice coming over the police radio sounded so f*cking Canadian, that's how. Trust me when I say it's a safe bet you'll never hear anyone connected with the Chicago Police Department saying "oot" or "aboot" instead of out or about.
Come on, Sci Fi channel. If you're going to shoot in Toronto, at least hire a few authentic Chicagoans to sprinkle the dialog with an occasional "over by", "bustout" or "jagoff."
