Implied conditions as to quality or fitness
18 Subject to this and any other Act, there is no implied warranty or condition as to the quality or fitness for any particular purpose of goods supplied under a contract of sale or lease, except as follows:
(a) if the buyer or lessee, expressly or by implication, makes known to the seller or lessor the particular purpose for which the goods are required, so as to show that the buyer or lessee relies on the seller's or lessor's skill or judgment, and the goods are of a description that it is in the course of the seller's or lessor's business to supply, whether the seller or lessor is the manufacturer or not, there is an implied condition that the goods are reasonably fit for that purpose; except that in the case of a contract for the sale or lease of a specified article under its patent or other trade name, there is no implied condition as to its fitness for any particular purpose;
(b) if goods are bought by description from a seller or lessor who deals in goods of that description, whether the seller or lessor is the manufacturer or not, there is an implied condition that the goods are of merchantable quality; but if the buyer or lessee has examined the goods there is no implied condition as regards defects that the examination ought to have revealed;
(c) there is an implied condition that the goods will be durable for a reasonable period of time having regard to the use to which they would normally be put and to all the surrounding circumstances of the sale or lease;
(d) an implied warranty or condition as to quality or fitness for a particular purpose may be annexed by the usage of trade;
(e) an express warranty or condition does not negative a warranty or condition implied by this Act unless inconsistent with it.
Remedy for breach of warranty
56 (1) If there is a breach of warranty by the seller, or if the buyer elects, or is compelled, to treat any breach of a condition on the part of the seller as a breach of warranty, the buyer is not merely because of the breach of warranty entitled to reject the goods, but the buyer may
(a) set up against the seller the breach of warranty in diminution or extinction of the price, or
(b) maintain an action against the seller for damages for the breach of warranty.
(2) The measure of damages for breach of warranty is the estimated loss directly and naturally resulting, in the ordinary course of events, from the breach of warranty.
(3) In the case of breach of warranty of quality, the loss is, unless there is evidence to the contrary, the difference between the value of the goods at the time of delivery to the buyer and the value they would have had if they had answered to the warranty.
(4) The fact that the buyer has set up the breach of warranty in diminution or extinction of the price does not prevent the buyer from maintaining an action for the same breach of warranty if the buyer has suffered further damage.
