If you never declared to the CRA that you have left the country on your T1, then they will still think you are resident and be wondering why you haven't filed a T1 since. So yes, it could make a big difference.
Also the bank won't ncessarily assume that you are non-resident, you have to tell them. If you receive an NR4 every year instead of a T5 then they have put you down as non-resident (assuming you have a Canadian dollar account). Those T5s go to the CRA, so they will be expecting to see a T1 filed under your SIN to cover them.
You will be assessed a late filing fee for every year you failed to file, if nothing else.
