Does a Retroactive Denial of Coverage Bar a Plaintiff from Suing in an MVA?

Short answer, No. Or at least that is the answer in the case of Alof v. Ikeno, 2014 ONSC 2087 (CanLII)

In this case, Matheson J. considered section section 267.6 of the Insurance Act in the context of a retroactive denial of motor vehicle insurance coverage by a plaintiff’s insurer on a summary judgment motion brought by the defendant.
