Section 111 - Lay opinion

(1) A witness who is not testifying as an expert may give testimony in the form of an opinion or inference only if

(a) the opinion or the inference concerns matters perceived by the witness, and

(b) the testimony in the form of an opinion or inference is helpful to the witness in giving a clear statement, or is helpful to the Court or tribunal of fact in determining an issue.

(2) The matter on which the witness bases the opinion or inference need not be disclosed before the witness states the opinion or inference, unless the Court otherwise determines, but the witness may be examined by a party concerning the basis for the opinion or inference and the witness shall then disclose that basis.
