We have not yet received confirmation that the company really has gone bankrupt. But LM Sauvé was replaced because its performance was unsatisfactory. They were not working to the schedule and no progress was being made. When we asked for explanations, when we wanted to know their plans, how they proposed to make up for lost time and to manage all the subcontractors, they really had no convincing answer.
It is just a theory on my part, but I suspect that LM Sauvé was very busy with the city hall in Montreal. They were not making enough effort. For us, it was very simple: if a contractor does not perform, the responsibility for the work is taken away.
