The Rideau Transit Group will pay for repairs after two rock bolts related to the Light Rail Transit tunnel excavation penetrated the parking garage wall of the Sun Life Building on Queen Street, the City of Ottawa said Wednesday.

"There are no risks to the integrity of building’s foundation and there was no other property damage," Gary Craig, the acting director of the city’s rail implementation office told CBC News in an email.

He said that RTG will revise its methodology to install rock bolts, which are used to stabilize rock excavations, to ensure this type of incident does not happen again.

City of Ottawa staff visited the parking garage and are working with the building’s property managers to ensure all necessary repairs are made, Craig said.
