Just another question , Is it ok that I file taxes even i'f i'm not considered a tax resident?
during 2015 , we only stayed for 3 weeks and returned home.
my wife lived in 2016 for 4.5 months and I lived for 2.5 months. and my wife used health card during our child birth
in 2017 also my wife used card at november and december .
one accountant told me I do not have to file taxes for theses years but i'm going to check with another as i'm afraid because my wife used her health card we might have to file.
The main reason of my concern is of course not for the sake for the sponsorship application but because i want to make a correct start at canada and also during citizenship i understood that you should filed your taxes correctly to apply .
thanks
Aside from the immigration matters, you should note that your wife has likely committed healthcare fraud, which is a very serious crime. Provincial health coverage has residency requirements and from what you've said, your wife did not meet those requirements when she came to Canada to give birth and therefore did not qualify for coverage.
