In Landbouwbedrijf Backx BV v R, 2021 TCC 2, the court held that the CRA was not bound by a section 116 “letter” it had issued that had found, in effect, that the taxpayer was not a resident of Canada. The CRA was entitled to assess the taxpayer later as a resident of Canada despite the letter because it was only for “reporting and collection purposes”.
