Lin v. Weng, [2020] O.J. No. 5532, 2020 ONSC 7137, Ontario Superior Court of Justice, November 23, 2020, A. Pinto J.

The insured and insurers each sought summary judgment in respect of a home insurance coverage dispute.

In the underlying action, the insured homeowner rented a bedroom to a tenant, and the tenant subsequently attempted to extract resin from marijuana in the basement of the home, causing an explosion and fire that destroyed the property.

The insurer denied the insured’s property loss claim, relying on the policy’s marijuana exclusion clause.

The fire occurred, and the action was commenced, prior to amendments to Ontario’s Insurance Act that were designed to protect innocent persons coming into force.  The new provision provided protection to innocent persons stipulating that exclusions for loss caused by a criminal or intentional act applies to only those who caused, consented or abetted the act.

The court found that the amendment did not apply retrospectively, and the claim was excluded from coverage by the marijuana exclusion.
