An LRT tunnelling crew has gone through a wall underneath a Queen Street building.
CTV Ottawa reports it happened in the parking garage below Sun Life Financial.
The damage from two rock bolts has not hurt the integrity of the building and did not affect anything inside the garage.
The Rideau Transit Group is reassessing how to continue with the tunnelling work. The City says RTG will be paying for any repairs associated with the incident.
