If the building respects the zoning theres almost nothing the city and neighbours can do.
Since there was a consultation though, it is probably because the developpers asked for derogations to the zoning code. This means the city could refuse the project based on many different reasons and negotiate for changes.
Direct neighbours of the project can also sign a petition and if 10% of them oppose the derogations, then the project has to go through a referendum or has to go through consultation.
Honestly I dont properly know all of this, so I would love for someone to correct me or add information.
You are pretty spot on but I believe that some boroughs like Pierrefonds-Roxboro have changed the process. And this project is the first one where they are using the new process. Before , their would be a public consultation on a project, after that the city gave residents 2 weeks to gather the required signatures (I believe it was less than 10% as usually 12-15 signatures suffice) to request a referendum. Getting these signatures would be enough to kill the project as referendum would be seen as too costly for the city.
But now they put up a QR code in front of the lot of the proposed project and you can simply snap it , go to the link and view the project and answer the survey. This gives the developer and the city a chance to foresee whatever resistance and opposition they might get from neighboring residents. They then can review the project before presenting it at a public consultation and with better support from the community due to the earlier input they can avoid a referendum.
Let these guys soften the blow to residents. Whatever gets built here is the MINIMUM that any of the projects will get so I hope they get the 6 they ask for. Banque Nationale and Table du Pêcheur will stand to benefit from it. Brivia can then go WILD almost.
