/ 04 — QuestionsFrequently asked

Why buy the Ontario bundle instead of individual city lists?+

The full province list costs $19. Buying 300 cities individually at $9 each would cost $2,700. The bundle gives you every general contractor in Ontario, from major hubs like Thornhill (3,203 contractors) to smaller markets, in one verified CSV file.

What data is included for each general contractor?+

Each record includes name, phone, address, email (where available), website, and Google rating and review count. 54% have corporate email addresses, enabling direct B2B outreach to project managers and owners.

How often is the Ontario dataset updated?+

We refresh all provincial data quarterly by scraping and verifying current Google Business Profile information, ratings, reviews, and contact details. You receive the most recent snapshot when you download.

Can I download the data immediately after purchase?+

Yes. Your instant CSV download is available immediately after checkout. No waiting for manual processing or account approvals — import directly into your CRM, phone system, or outreach platform.

Which cities have the most general contractors in Ontario?+

Thornhill leads with 3,203 contractors (5.00-star average), followed by Amherstburg (1,001), Markham (903, 4.75-star average), Brampton (589, 4.82-star average), and Plantagenet (308). Smaller markets are also included — 300 cities total.

/ HelpCommon Questions

How do I choose a reliable general contractor in Ontario?+

Start with the rating — look for a general contractor holding 4.5 stars or higher with a healthy number of recent reviews, which signals consistent, current service. Confirm they're properly licensed and insured for the work you need, and read a few reviews to see how they handle problems, not just praise. The listings below are sorted by Google rating to make this easier.

What's the typical cost of a general contractor in Ontario?+

Pricing varies widely by the scope of the job, materials, and how urgent the work is, so there's no single rate. The most reliable approach is to contact two or three general contractors directly for a quote on your specific situation. Use the "View on Google Maps" or "Visit Website" buttons on each listing to reach out.

Are these general contractors verified?+

Yes. Every listing is sourced from public Google Business Profile data — business name, rating, and review count — and refreshed monthly so closed or relocated businesses drop off. We show only what's already public; we don't add or alter business details.

How can I contact a general contractor?+

Click "View on Google Maps" to get directions, hours, and the business's public contact options, or "Visit Website" to reach them online. We don't publish private phone numbers or email addresses here — the business's own Google profile and website are the right place to get in touch.

I'm a business owner — how do I update or remove my listing?+

Email support@publicleads.com with the subject "Removal Request" and include your business name and city. We process removal and correction requests within 48 hours.
