The non-resident taxpayer received payments on a non-interest bearing mortgage between 1964 and 1969 after showing the deed to a Revenue Canada assessor, who indicated that s. 16(1) would not apply. In 1971 Revenue Canada assessed on the basis that ss.16(1) and 214(2) applied. Decary, J. stated in obiter dicta: "It cannot be said in the present instance that due despatch has been used by the Minister: 7 years after the deed, 2 years after the last instalment. Despatch means promptitude, speed."
