If CRA ask about presence in Canada

[Hasher]

Friends

CRA send a letter asking to prove period of presence or send money back. Very much willing to return all money back but that will close the case.

Well you're missing a key fact in your post - were your a Canadian resident for the year?

See http://www.cra-arc.gc.ca/tx/nnrsdnts/ndvdls/nnrs-eng.html for some guidance on how the CRA calculates residency.
