According to the Canada Steamship rules (Canada Steamship Lines Ltd v. The King (1952) ) , a clause which purports to exempt one party for liability in negligence will be construed to cover negligence liability if it expressly exempts such liability. Exempting liability for 'loss whatsoever or howsoever occasioned' is not sufficiently express. Such a clause will only be construed to cover negligence liability where the words used are wide enough in their ordinary meaning to cover negligence liability, and:

A) fhe exemption can cover other types of liability.
B) the exemption cannot cover other types of liability.
C) the exemption is a reasonable one.
