David Heurtel said for the first few decades after the stadium was built, workers found an average of 30 to 40 rips in the roof each year.
Since then, the frequency of tears have jumped. Between November and May, more than 2,700 rips were found during daily inspections — more than double the number found last year.
Heurtel said the rips are usually only a few millimetres or centimetres long and are patched up during daily inspections. In fact, he said the building is one of the most monitored in the city when it comes to public safety.
Despite that, concern about safety and reliability have prompted organizers to start hosting their events elsewhere.
The Montreal Alouettes had approached Heurtel about hosting the Grey Cup in 2017 at the stadium, but Heurtel says he doesn't know if the stadium will be able to follow through.
“The CFL needs to have a guarantee of a 40,000 seats plus venue to even consider the candidacy. And right now we cannot give them any type of guarantee,“ he said.
Heurtel says he's in discussions with the province to get the money needed to replace the roof.
He says it could cost anywhere between $200 million and $500 million.
But Heurtel says it's worth it.
"This is an investment," he said. "We can have a lot more jobs generated by this, a lot more tourism."
"It's our international symbol."Suggest a correction
