The appellant, FNX Mining Company Inc., appealed an order from a building inspector requiring building permits for a generator structure and several trailers at its mine site.
The generator, providing standby power, was remotely operated and not designed for human occupancy, though maintenance staff entered periodically when it was off.
The trailers served as offices, lunchrooms, and first aid stations, were movable but secured for periods with utilities attached.
The court, applying a reasonableness standard, found the generator was not a "building" under the Building Code Act, 1992, as its transient occupancy and regulation by other safety regimes made the building permit requirement unreasonable.
However, the trailers, being secured for periods with utilities and used for regular human occupancy, were deemed "buildings" requiring permits.
The appeal was allowed in part.
