Sometimes identifying "Canadian" productions gets down to what you want to believe. I know people who will identify a co-production as "American" if they like it, and dismiss it as "Canadian" if they don't. Who knows what the future holds for Canadian genre TV? Maybe on the horizon is a Canadian genre series that isn't just grudgingly set in Canada, but unapologetically so.
A "crossover" is when characters from one series/property appear in an unrelated series/property. In comic books, the "shared universe" idea is so intrinsic, characters regularly guest star in each other's magazines. There are different reasons for doing a TV crossover. The first is just for the fun of it.
Orphan Black is about clones and conspiracies. Part of the series' appeal is doubtless its gimmick. The twinning process -- wherein an actor plays opposite himself -- has been around for decades, but Orphan Black does it better than almost anything before. Even when the clones hand each other glasses you forget special effects are involved!
Captain Canuck was the first Canadian super hero since the 1940s. And he's the Grand Old Man compared to later characters like Northguard or the American-published Vindicator/Guardian (or whatever he/she's called these days) of Alpha Flight. And this Canada Day, he returns in his very own web series.
At heart, every story has probably been told, so it's in the details it's kept fresh. When Canadian filmmakers refuse to set their productions in Canada, they are basically announcing: "We have no intention of doing anything fresh with this material." If the creators aren't willing to fight for something as rudimentary as the setting, can we really expect them to fight for other things? Is the fact that so many of these filmmakers are unwilling to set their stories explicitly in Canada part of the reason why there are so few Canadian series and movies fronted by non-white actors? 'Cause that might be a fight with executives, too.
Canadian series have a history of pretending they're set in America. Where they are supposed to be set -- well, that's a fascinating topic. In recent years we've also seen what could be called the "soft" Canadian setting. Series which admit they are set in Canada but in a way that a lot of viewers probably wouldn't pick up on.
Truly, this joint BBC America/Space Channel venture is what productive TV collaborations should aspire to. It's like the joining together of all of western civilization: you can literally sense the Britishness in the show's aesthetics (not unlike Doctor Who), the Canadianness in the cast and scenery (shot in a very gritty Toronto) and the American touches of fast action and zippy, perfect dialogue.
