"there seems to be a presumption now that you shouldn’t say anything if you can’t embrace the totality of the Canadian experience."'

Lol! Nice to see a representative of the Left get a dose of his own medicine. After decades of attacking any viewpoint as not "inclusive" enough, it's their turn to they find out how it feels to not be able to ever be inclusive enough to satisfy the critics...

Yes, one cannot possibly give an overview of Canadian history, or any other history, in a few hours, while including every possible group and detail. 

Maybe the problem is trying to cover all of Canadian history in a single series.

 The US, as pointed out, has a whole industry cranking out detailed historical documentaries on every aspect of American history: whole multi-episode series just on the Civil War, or the Black Experience, etc. We would need to do the same, i.e. one series on each different region and period, etc., for all possible viewpoints and details to be fully represented.
