Find out what is actually protected
An old building is not automatically a designated heritage property, and a designation can apply to particular features or a broader place. Obtain the relevant designation, listing or statement of significance and ask the municipality which approvals apply to the proposed work. Keep those documents beside the damage assessment.
Parks Canada’s conservation standards emphasize understanding heritage value and conserving character-defining elements. Use that framework to discuss the property; local legal requirements and approvals still need to be confirmed for the actual address.

Stabilize without losing the record
Urgent work may be needed to protect people or prevent further loss. Coordinate it with the responsible authorities and qualified professionals. Where documentation can be collected safely, identify significant elements before removal: location, dimensions, profiles, materials and photographs. Label anything removed for assessment or storage so it can be traced back to its original position.
Do not delay necessary emergency action to take photographs. If access is restricted, ask the professionals doing the authorized work what record they can provide.
Separate repair, replication and replacement
| Option | Question to resolve |
|---|---|
| Retain and repair | What sound material remains and what conservation method is appropriate? |
| Remove temporarily | How will it be labelled, protected, stored and returned? |
| Replicate a lost element | What reliable evidence establishes the profile, material and finish? |
| Replace with a different assembly | Which heritage, technical and approval implications must be reviewed? |
Avoid choosing replacement simply because a modern catalogue product is easier to price. Equally, do not retain an element without the relevant condition and safety assessment. Ask for a written rationale linking the proposed treatment to evidence.
Price the uncertain work transparently
Use allowances only where the scope is genuinely unresolved and state what will resolve them: a cleaning trial, opening-up, specialist report or approval. Keep owner-selected improvements separate from restoration of damaged character-defining elements. Record the effect of any revised method on cost, time and retained material.
At handover, collect conservation reports, approved repair details, photographs before concealment, product information and a record of stored or reused components. The rebuilding guide and scope register help connect these decisions to the wider project.
