To my insurer or broker,
Re: heritage status of 852 Hellmuth Ave, London, Ontario
Status
According to the City of London — Heritage Parcels (as of October 12, 2026), this property is designated under Part IV (individual property) of the Ontario Heritage Act, by-law LSP3217352. It is recorded as Gibson Property. Source: https://www.arcgis.com/home/item.html?id=ac8425f044e1477b849c53f37df11eff
What this status requires
Designation protects the heritage attributes described in the designating by-law. Alterations that affect those attributes need a heritage permit from the municipality, and demolition needs council's consent.
It does not require the owner to rebuild a replica after a loss. In the Province's words: “The designation by-law does not require the owner to replicate any lost heritage attributes. A replacement building can be of a different design.” and “Insurance premiums should not go up because of a heritage designation.”
The building
Details insurers ask about for older buildings (filled in by the owner):
- Electrical service (60-amp or 100-amp and up) and wiring type: knob-and-tube or aluminum wiring is a common reason for refusal:
- Plumbing: galvanized steel pipes corrode from the inside:
- Heating: oil tank age (over 25 years is a concern) and any wood stove (WETT inspection):
- Roof age and condition (over 20 years raises the risk of leaks):
- Recent upgrades, with dates, receipts and photos:
