I haven't heard about any yet. But you've got to think they'll be filming on location since Tru's cases always take her loads of different places in every episode.
They film at Lions Gate Studios in North Vancouver (555 Brooksbank Avenue).
It's a big lot, but maybe you could see something? Some times they put up backdrops in parking lots and film right outside their studios or have backlot areas with fake streets setup for example. Usually passers-by can't see anything, but at Sunset-Gower in Hollywood, for example, you can see American Dreams filming in the parking lot all the time.
There's a site called HollywoodNorthReport.com that has information on location filming and a forum that might eventually have information. But they're more obsessed with movies filming than tv. I've posted on there already about TC. Recently one person reported some location filming in Vancouver and the admin brushed it off as only being the new UPN show Jake 2.0. All they seem to care about is Will Smith's movie I Robot and things like that. But Eliza's a bigger star so hopefully we can get that site to start showing interest in finding TC location shoots in advance.
I really want to go up to Vancouver this fall on vacation. I love British Columbia and it'd be great if I could see some TC location shoot.
