The hole appeared on the corner of Ste-Catherine and Guy Streets on the morning of Aug. 5, swallowing a backhoe and the worker inside.
The worker escaped unharmed, and crews eventually lifted out the backhoe, but the repair work has drawn on.
The street closure has hurt the local businesses that normally enjoy high traffic during the summer season.
Dominique Girard, manager of the 3 Amigos restaurant, says his patio is typically packed with people at this time of year.
“Usually at lunchtime, and evening, I have three servers for the lunch, and three servers for the night,” Girard says.
“Now today I have three tables, only one server, it's [certain] that some employees are penalized. I cannot keep everybody because there's nothing to do,” he said.
The city says the repair work is a complicated process.
Crews had to first pump water out of the sinkhole in order to asses the damage with a camera before they could start repairs.
Workers are on the scene 16 hours a day, and the city says it will take at least one more week to patch up the road.
