Filming location?

Probably Van... with a fast flyover of downtown Seattle and the Space Needle...

Looks ot me like St. John, same place they film Republic of Doyle, on CBC. I recognize some of the same storefronts/locations. Possibly. Otherwise, yeah, most likely Vancouver if not St. John

As a long time Seattle resident and visitor of Vancouver? I'm saying Vancouver and probably other BC locations. The waterfront is clearly not Seattle and the buildings look like some I've seen in Vancouver. The "public market" (guessing it's called that because they didn't get permission to use Pike Place) looks an awful lot like the Granville Island Public Market in Vancouver, much more modern looking and there were no shots any of the famous bits that would identify it as Pike's Place.

Most of the shots I saw in the trailers that were "Seattle" looked as though they were altered too.

Just watching it now, and it's certainly not Seattle - even a detail as simple as the police cars is wrong.

My computer...

It looks like Vancouver to me, with an occasional shot of Seattle. I've lived in Seattle my whole life & I can assure you it's not Seattle.

North Vancouver. Lonsdale Quay is the public market standing in for Pike Place.

Absolutely North Vancouver. There is an early scene showing the Vancouver skyline across the harbour, another showing the Seabus sailing by, and I think the market was the Lonsdale Quay market which is right in the same area. No question it is North Van. These locations are also only a few miles from the big movie studio facility, so they kept it close to home.
