I’ve said this before, but it bears repeating: It isn’t "run-away production" that the American entertainment industry should be worried about. Hell, back in Toronto, we’re only now starting to get back into the game. If California governor Arnold Schwarzenegger and the "Blame Canada" doomsayers were really on the ball, they’d realize that the Canadian threat to Hollywood comes not from without, but within.

Welcome once again to the "Frostback Report," my annual wrap-up of Canadian talent featured on new U.S. fall-season shows. The tally this year is only 13, down perhaps a half-dozen from the totals of each of the past three seasons. But that drop is somewhat compensated for by the fact that so many of those already entrenched remain in key roles in shows still on the air.

Tom Cavanagh’s Ed may be gone, but Eric McCormack still rules on Will & Grace, as do Kiefer Sutherland and Elisha Cuthbert, the father/daughter duo of 24, Jill Hennessy on Crossing Jordan, Sarah Chalke on Scrubs, Ottawa-born Donal Logue on Grounded For Life, Gregory Smith and Emily VanCamp on Everwood and Emmy nominee Victor Garber on Alias.

Kristin Kreuk is still breaking hearts on the Vancouver-shot Smallville, Vanessa Lengies is still bopping away on American Dreams and Will Sasso has gone from Mad to Less Than Perfect, with Yanic Truesdale seeking new levels of snide on Gilmore Girls and Jeremy Ratchford growing into his role on the very familiar-sounding Cold Case.

Relative newcomers (since last season) to the American airwaves include Ontario’s own Will Arnett and Michael Cera, both now basking in Emmy adulation (seven nominations) for the critically acclaimed but viewer-deprived Arrested Development. There’s also Molly Parker on the potty-mouth HBO western Deadwood, hot mom Kelly Rowan on the teen hit The O.C., and former 90210 poster boy Jason Priestley reporting for work on the Vancouver set of Tru Calling.

And this does not even take into account the cable infiltrations of Kenny & Spenny, from CBC to GSN, the arrival of The Trailer Park Boys on BBC America (and of their co-star/co-writer, Jonathan Torrens, on Spike TV’s reality spoof, Joe Schmo 2) and the snarky hep-cat patter of Kid In The Hall Dave Foley as host of the American Bravo’s unlikely hit, Celebrity Poker Showdown.
