Earlier this year, Quebec announced it would cost close to $870 million to build a new roof at Montreal’s Olympic Stadium.
According to the Journal de Montréal, the province will now have to spend close to $1 billion after they failed to include several essential costs like mechanical, electrical and ventilation work in their estimate.
In February, the Quebec government said that major renovations would be needed to replace the roof and the technical ring supporting the new roof.
According to the Journal de Montréal, the additional work will cost around $130 million, on top of the $870 million already needed for the roof.
Just this week, the Quebec government granted the Olympic Park $40 million for renovations and cleanup of the sports centre and main tower after a fire last month caused major damage.
