Markham has four heritage conservation districts: Markham Village, Unionville, Thornhill and Buttonville. According to the City's heritage services page, changes to a building's exterior, additions, garages and other accessory buildings, new construction and demolition there need a heritage permit, and each district has its own plan. For a trade or main-street business, that single fact reshapes how customers choose who to hire. This guide explains how, and what to do about it.
As always, we're writing about marketing. Nothing here is planning or permit advice. Confirm every requirement with the City of Markham directly.
Why heritage buyers behave differently
Answer first: a heritage-district homeowner is buying reassurance as much as a service. When exterior work needs approval, the homeowner is taking on extra time, paperwork and the risk of getting it wrong. They're likely to research more, ask more questions and favour the firm that seems to understand the process.
That changes the marketing in three ways:
- Price matters less than confidence. Homeowners still compare quotes, but a cheaper firm that seems unsure about the district's expectations often loses.
- The decision takes longer. Weeks or months can pass between first contact and signed work, especially if a permit application is involved.
- Proof travels by word of mouth. Heritage streets are compact. A well-done porch or roof is seen by every neighbour walking past, and referrals follow.
The trades and businesses that benefit most
Answer first: any business whose work changes what a heritage building looks like from the street is in the frame. That typically includes:
- roofers, especially those who work with traditional materials
- window and door specialists, including restoration and custom replacement
- masons and brick repair
- exterior painters and carpenters for porches, trim and fencing
- eavestrough and exterior metalwork
- landscapers and hardscapers working on front yards
- sign makers and shopfitters for main-street storefronts
Interior trades such as plumbers, electricians and HVAC firms are less affected by the permit process, though older homes in these areas can bring their own challenges. They can still win work here by showing they're careful with older buildings, for example by protecting original floors and trim.
What to show, and what not to claim
Answer first: show real past work; never claim approvals or expertise you can't back up.
What to show
- A dedicated heritage page. One page on your site about working on older homes in Markham's heritage districts, with photos of your own projects. Name the district only if you've genuinely worked there.
- Process, in plain language. Explain how you work with homeowners who need a permit: when you visit, what drawings or photos you can provide to help the homeowner's application, and how you handle the waiting time. Be careful to say the homeowner deals with the City, unless you genuinely handle submissions.
- Before-and-after photos. Taken from the street, so readers can see the result as neighbours will.
- Materials knowledge. Brief notes on the materials and methods you use for older buildings, without technical claims you can't support.
What not to claim
- "Heritage-approved", "City-certified" or similar wording, unless the City or another authority has actually given you such a status. The City approves permits for properties, not trades.
- Promises that a permit will be granted.
- Experience with a district where you haven't worked.
On a street where neighbours compare notes, one overclaim can cost you every house on the block.
Search and listings in heritage districts
Answer first: heritage homeowners search for the problem and the place together. Expect searches like "slate roof repair Unionville", "wood window restoration Markham Village" or "heritage porch Thornhill".
Practical steps:
- Mention the district by name on the right page. Not stuffed into every paragraph, but used naturally on the heritage page and in project descriptions.
- Add projects to your Google Business Profile. Photos and short updates about completed heritage work help both relevance and trust.
- Ask heritage clients for reviews that mention the work. A review that says "restored our original front windows on our Unionville home" is worth more than a generic five-star note. Never write reviews yourself or offer rewards for them.
- Be realistic about Thornhill. It straddles the Markham-Vaughan boundary, so check which municipality a property is in before you talk about local rules. The City's heritage districts map layer shows the Markham boundaries.
Main-street storefronts in heritage districts
Answer first: on Main Street Unionville and Main Street Markham, the setting is part of the attraction, so marketing should sell the visit, not just the product.
- Show the street. Photos of your shopfront in context, at different times of year, help visitors picture the trip.
- Answer the practical questions. Parking, accessibility, weekend hours and what's nearby.
- Plan around busy periods. Summer weekends, festival days and the holiday season bring visitors; quieter weekdays need offers for locals.
- Check before changing your frontage. New signs, awnings or exterior paint may need a heritage permit. Build approval time into any rebrand.

A worked example: is a heritage push worth it?
Answer first: run the numbers before you commit, because the pool of homes is limited.
Imagine a window and door company. An average heritage window restoration job is worth $8,500, with a 35% margin, so roughly $2,975. If the firm wins one such job every two months from a focused heritage page, a few reviews and some modest search ads costing $600 a month, the yearly picture looks like this:
- Six jobs × $2,975 = $17,850 in margin
- Twelve months × $600 = $7,200 in marketing cost
- Net contribution before referrals: about $10,650
Add even two referral jobs from neighbours and the case strengthens considerably. If the firm can only win one heritage job a year, it's probably better to spend that budget elsewhere.
Common mistakes
- Using the same page for every district. Markham Village and Buttonville are different places; write about the work you've done in each.
- Ignoring the waiting time. If a homeowner needs a permit, follow up politely every few weeks rather than assuming they've gone elsewhere.
- Overloading the site with heritage language. Keep it plain and specific; readers can tell when a company is reaching.
- Forgetting the rest of the city. Heritage work suits some businesses as a specialism, but most need a healthy flow of everyday jobs too.
Next steps
If heritage work suits your business, start with one strong page and a handful of real photos. Our local search service can build the rest around it. Read about each heritage district and the surrounding communities on the areas page, or see our other guides. We are a marketing service only, not a contractor, and we don't handle permits or planning applications.
Frequently asked questions
Do I need special qualifications to advertise heritage work in Markham?
We can't advise on qualifications or permits. What we can say is that you should only claim experience you can show, such as past heritage projects with photos. For requirements, contact the City of Markham's heritage staff.
Is heritage-district marketing worth it for a small trade?
It can be, if your work suits older buildings and you're patient. The number of homes is limited, but jobs can be larger and referrals travel quickly among neighbours on the same streets.
Can I put up a sign or change my shopfront on Main Street Unionville?
Exterior changes in heritage districts may need a heritage permit. Check with the City before you order anything, and allow time for the review.
