Interesting. The creation of the official accounts back to the Obama/Stephen Harper era. So that's one thing to consider how relevant the location data is to current day.

Maybe the legacy Canadian media outlets farmed their initial social media presence to a US contractor/communications agency? Or out of a foreign bureau in Washington?

The CBC one is probably the most surprising. It's long been known that the current head lives in Brooklyn, Catherine Tait. But pretty sure 2007 predates that bitch.
