MONTREAL - A coroner says a Montreal parking garage that collapsed and killed a man was poorly built and badly maintained.

Coroner Catherine Rudel-Tessier has concluded the 2008 accident was avoidable.

She says the multi-storey garage was held together with concrete slabs of different thickness and with cardboard moulding.

She says the structure was in a sorry state and had surpassed its useful life.

It was built around 1970.

In a newly released report, Rudel-Tessier is recommending changes to the Quebec building code to tighten rules for inspections.

Saleh Khazali of Montreal was crushed in November 2008 when a slab of concrete collapsed onto his car and crushed it, while sending other vehicles tumbling onto the storey below.
