Tip Top Tailors Limited v. Minister of National Revenue, [1957] CTC 304 -- text
RAND, J.:—The appellant company deals in large scale manufacture of wearng apparel in the course of which quantities of cloth are purchased in lots from Great Britain. Its ordinary practice, prior to January 1948, was to pay for each lot according to the terms of the invoice by an individual purchase of sterling at the rate of exchange then prevailing. In that month the officers of the company, foreseeing the likelihood of a devaluation of sterling, made preparations to avail themselves of the benefit of that happening should it eventuate.
