Headline is weird.  Doesn't really pertain to the biggest focus of the piece, which is, from the writer's perspective, that Canadian film is definitely NOT "about us."

"Personal" movies are made here for a number of reasons.  Perhaps because they are more meaningful than Transformers V or whatever the big-bang computer generated visual-effects blockbuster happens to be at the moment.  

Perhaps because they are much CHEAPER than big-bang stuff.  Four or five actors, no CG needed, existing "sets" (real homes, offices, nice scenery.)  No huge budget needed for period-piece historical sets, either.  So, typically, set in 21st century reality. 

Another reason: Canadians don't really like their history.  They appear to be ashamed of it (needlessly) or "bored" by it (mistakenly.)  So, very few historical dramas, when we have lots available;  can give you a dozen in about 60 seconds flat--and it wouldn't include the Halifax explosion, either. 

Finally, small population; like U.S. movies.
