What it actually changes
Where CodesWise earns its keep
Schematic and DD code review
Ask 'Maximum travel distance to a single exit in a Group D office occupancy?' and get the clause, page, and the exception that matters for your floor plate.
OBC vs NBC differences
Ontario diverges from National in dozens of small ways, energy compliance, sprinkler trigger thresholds, exterior wall ratings. CodesWise picks the right edition for your jurisdiction automatically.
Multi-discipline coordination
When the structural engineer asks you for the fire-resistance rating between residential floors and you need an answer in this meeting, type the question.
Accessibility and barrier-free design
Get the actual OBC 3.8 / NBC 3.8 requirements with exact dimensional tolerances, not guesses from a CEU you took five years ago.
