Expert Report

Peller v. Ogilvie-Harris 2018 Ont SCJ

To be valid, an expert report must opine on the key issues on which testimony is to be given. The testimony does not have to be within the four corners of the report, but must articulate the opinion and the reasons for it. A reader cannot be left to guess about what the expert means. In this case, the report did not opine on causation and the expert was not allowed to do so in testimony.
