To successfully oppose summary judgment, a defendant need only satisfy the court that: (1) he has fully disclosed the nature and grounds of his defence and the material facts upon which it is founded; and (2) on the facts so disclosed, he appears to have a defence which is bona fide and good in law. A defendant succeeds in having summary judgment dismissed if there is a mere possibility of success, a plausible defence, a triable issue, or a reasonable possibility that an injustice may be done if summary judgment is granted. Where an agreement's true characterization (as lease or sale) is disputed and supported by evidence including contemporaneous documents, minutes showing sales negotiations, payment designations as 'rent to buy', and acceptance of lump sum settlements, a triable issue exists that cannot be resolved on summary judgment.
