"Call Me Maybe" video location
The director of the video mentioned in an interview that it was filmed in Vancouver. A few more google searches later, and I found a YouTube comment mentioning that it was filmed in Langley (near Vancouver). I simply bounced around from street to street until I found the match.
I was hoping to stumble across either the Camaro or the Mustang used in the video, but they are not around. The old VW Jetta in the next-door neighbor's driveway does appear in the video.
Ryan's house from "Wilfred"
Almost a year later, the FX network began showing reruns of the first season a few weeks before the debut of the second season. Then I saw my lucky clue in one of the early episodes (#3?). A garbage can in the alley behind Ryan's house had an address painted on it (house number and street name). I compared the neighborhood in Street View to scenes from a few episodes to confirm the location.
I recently read that the show's location manager, Briana Burke, won an industry award for her excellent work with the residents of this neighborhood during filming. While I wouldn't blame a fan of the show to swing by here to see the neighborhood in person, I would hope that you do so on your best behavior.
