The man driving the bust that hit Cassi Lam 11 days ago has now been charged with careless driving.

The accusation comes amid new calls for changes at the roundabout, where the student suffered serious injuries.

Police won't release the name of the man they have charged, only saying that he is 39-years-old and from Hamilton.

Ever since the incident on October 7, there have been heated debates over the region's roundabouts. On Tuesday, that debate spilled over into the regional council meeting.

"I hear transport trucks trying to stop, coming down that hill. And I don't know what they do on wet days" says Regional Councillor Geoff Lorentz.

Kitchener Mayor Carl Zehr says "I think there has to be active and aggressive enforcement in the roundabout area, and perhaps for a time, zero tolerance. Ignorance about how to use a roundabout is no longer an excuse."

The optics for the region are made even worse by the fact that the driver who sparked all this is a regional employee.

"As a result of the investigation, Regional Police have laid charges against the 39-year-old driver of the Grand River Transit bus" says Inspector Greg Lamport.

Eric Gillespie, Director of Transit Services says the driver remains employed.

"The employee continues to be on a paid leave, while we complete our investigation. Now that we have the information from police, that will come together with our own internal investigation."

At a meeting Monday night, the Catholic School Board went as far as to ask the region to scrap plans for a similar roundabout near a school in Cambridge. They also want changes in Kitchener says John Shewchuck with the school board.

"There's a number of steps that the region has undertaken to providing crossing guards for the students, to doing a speed study to the speed on Homer Watson Boulevard."

On Tuesday, it became clear the plan for crossing guards had flaws. The Highway Traffic Act doesn't allow them to work on roads as fast as Homer Watson.

Councillors moved to reduce the speed at the roundabout to 50 kilometers an hour.

Speed should be reduced immediately on Homer Watson. I don't see the need to wait for a report" says Regional Councillor Rob Deutschmann.

While councillors were very clear they want the speed limit reduced, it won't happen until staff can formally write up the bylaw, and council can then approve it.
