Hi, Fake.  
About "relevancy."  Got a hunch--hard to prove because polls haven't asked us the question you raise--maybe Canadians feel "news", especially news emanating from Ottawa ISN'T relative to them. B.C. fires aren't seen as relevant to Albertans (until smog clouds the air in Calgary). Kinder Morgan's B.C. pipeline isn't relevant to New Brunswickers.  Issues in PEI (I'm a B.C. boy, so what would I know?) isn't  relevant to mainlanders.  FN stories aren't news anymore to anyone anywhere anymore.

My theory on Trump-mania on airways and newspaper pages: 
1. Most national U.S. stories are big news to Canucks anyway, for all sorts of reasons.
2. Whitehouse stories are bigger news than most national U.S. stories.
3. Trump stories are bizarre, outrageous, frightening...choose your modifier. And finally...
4. They are safe(r) than Ottawa political stories because they are AMERICAN, not Canadian.  We can pontificate and posture about them without end...and without effect.  Great fun, eh?
