Minister of National Revenue v. Haddon Hall Realty Inc., 62 DTC 1001, [1961] CTC 509, [1962] S.C.R. 109 -- summary under Improvements v. Repairs or Running Expense

In finding that expenses incurred by the taxpayer in replacing stoves, refrigerators and window blinds which had become worn out, obsolete or unsatisfactory to the tenants of its apartment building were non-deductible, Abbott J. stated (p. 1002):

"Expenditures to replace capital assets which have become worn out or obsolete are something quite different from those ordinary annual expenditures for repairs which fall naturally into the category of income disbursements."
