Short answer
St. Thomas is an independent city and the seat of Elgin County, with about 42,900 residents at the 2021 census. It has its own municipal rules for driveways and permits, separate from the City of London, and much of its housing stock is old, so replacement and repair work is common.

What this means for concrete work
Older neighbourhoods tend to have older driveways, walks and steps that have been through many winters. That makes repair or replacement one of the most common questions, especially cracked front steps and walkways, settled driveway aprons and surfaces damaged by salt. Check the base and drainage, not just the surface, before choosing a repair.
On properties with heritage designation or in a heritage area, changes to the front of the house, including walks and entrances, may involve additional review. Ask the City of St. Thomas whether your property is affected before you change an entrance or a front walk.
Concrete in St. Thomas faces the same freeze-thaw and de-icing salt conditions as in London. The salt and frost damage guide applies here too.
Rules: who to ask
St. Thomas is not part of the City of London, so London's published driveway and boulevard rules do not apply to your property. Ask the City of St. Thomas about driveway width limits, entrance permits, boulevard or curb work and any building permits for structures. Provincial highways and county roads have their own authorities, so a driveway entrance on one of those roads may involve more than the municipality.
- What is the maximum driveway width on my lot?
- Do I need an entrance or curb cut permit?
- Is my property in a heritage area or designated?
- Who locates underground utilities before digging?

Frequently asked questions
Do London's driveway rules apply in St. Thomas?
No. St. Thomas is an independent municipality, so ask the City of St. Thomas for its own rules.
Are older St. Thomas driveways more likely to need replacement?
Older slabs have seen more freeze-thaw and salt cycles and may have thinner or less drained bases, so repair or replacement is common. A contractor should inspect before recommending either.
Do heritage properties have extra rules?
Possibly. Ask the City of St. Thomas whether your property is designated or in a heritage area before changing entrances or front walks.
