Langford is known for smooth sailing on the permit process. There must have been an architect on record. As the coordinating professional, it’s up to them to ensure everything is properly reviewed.
Municipal governments will have Civil Engineers on staff, and while they might (or might not) have a Structural Engineer on staff, I can't see them taking responsibility by second guessing every engineers report. From news reports in this case, the engineer was not authorized to approve/stamp the report. If there are issues with Langford's approval process, I guess we will find out in the court ruling.
