Who issues the permit in Lachute?
The urban planning department of Lachute. We prepare the plans the municipality requires, check its bylaws with you, and support you through the submission.

Yes. We draw plans anywhere in Quebec: conversations happen remotely, and we agree with you on travel when the survey of the existing building calls for it.
