Do you need a permit to install solar panels on your roof? If you’re ready to go solar, congrats! Before your panels go up and start saving you money, there’s an important step: obtaining the right permits.
Across Canada, whether in Toronto, Calgary, or Charlottetown, legal solar installation involves municipal approvals and electrical inspections. The good news? Once you know what’s required, the process is manageable, especially with an experienced installer.
This article breaks down which permits you need, who is responsible for applying, typical timelines, and how requirements differ by province, helping you go solar confidently and legally.
What Permits Do You Actually Need to Install Solar Panels?
There are two main types of permits most homeowners will need:
Types of Permits
- Electrical Permit: Required everywhere in Canada. It ensures your solar system is installed safely and up to code.
- Building Permit: Required if the installation affects your home’s structure—like reinforcing a roof or mounting racking.
Depending on where you live, you might also need:
Other Potential Requirements
- Zoning clearance (for homes in heritage districts or urban zones).
- Structural engineering reports (especially for older homes or snow-heavy regions).

Quick rule of thumb: If you’re installing solar panels on your roof, assume you’ll need at least an electrical permit, possibly both.
Who Applies for Solar Panel Permits?
In most cases, your installer manages the paperwork but it’s always wise to confirm that obtaining permits to install solar panels is included in your quote.
What a Good Contractor Does:
- Submits applications to the right municipal or provincial authority.
- Pays any permitting fees (or includes them in your invoice).
- Schedules inspections as required.
- Ensures everything is up to electrical and building code.
Tip: Ask this during the quoting process:
“Do you take care of all permitting and approvals, or do I need to do anything myself?”
Permitting for Solar Panels: What Changes by Province?
Permitting processes vary from province to province (and even city to city). Here’s a snapshot:
Province-by-Province Requirements
| Province | Electrical Permit | Building Permit | Notes |
|---|---|---|---|
| Ontario | Yes – through ESA | Sometimes | ESA inspection required before connection. |
| British Columbia | Yes – via Technical Safety BC | Yes in most municipalities | Some cities (like Vancouver) have additional solar bylaws. |
| Alberta | Yes – municipal level | Often required | Varies by municipality (e.g., Calgary vs. Red Deer). |
| Nova Scotia | Yes – NS Power rules | Likely | Must meet net metering + permit standards. |
| Quebec | Yes – via licensed electrician | Yes (RBQ rules apply) | Heritage zoning can affect timelines. |
| PEI | Yes | Often | Permit rules are tied to rebate eligibility. |
Real Example: In Toronto, you need an ESA permit and may also need a building permit if your racking system affects the roof’s structure. In Victoria, BC, your solar array must meet local aesthetic rules in heritage zones.
How Long Does It Take to Get a Permit to Install Solar Panels?
Typical permitting timelines range from 1 to 4 weeks, depending on:
What Affects Permit Timing?
- Your municipality’s review speed.
- Time of year (spring and summer are busiest).
- Quality of your installer’s application (incomplete drawings = delays).
Estimated Timelines
- Small town or rural: 1–2 weeks.
- Mid-sized city: 2–3 weeks.
- Large urban centre (Toronto, Vancouver): 3–4 weeks.
