A new report is dismissing a campaign by former regional chair Andy Haydon to choose buses over light rail.

The study by city staff says light rail is cleaner, more comfortable, and has financial advantages when compared to an expanded bus system.

Still, Haydon maintains buses are the best option for Ottawa transit users.

"Light rail is susceptible to weather conditions. We've seen it here, we've seen it in Finland," he told CFRA listeners on Tuesday.

In the event Ottawa gets pounded by another ice storm, Haydon said it would bring down important wires connected to the light rail system, creating a major problem for transit.

"We don't have that problem with buses, they just move around the problem," he said.

Haydon is credited with being the architect of Ottawa's bus transitway system.
