Do You Need a Permit to Replace Windows in Toronto?

Planning to replace your windows?

It sounds simple. Take out the old ones. Install the new ones. But in Toronto, there’s one important thing to check first. Do you need a permit?

In some cases, you do. And if you skip it, you could face fines or delays. You might even be asked to redo the work.

This blog will help you understand the rules. I’ll explain when a permit is needed, when it’s not, and what steps to take before you start.

Why Permits Matter for Window Replacement

Permits help protect homeowners. They make sure your project follows building codes and safety rules. These rules are set by the City of Toronto and the Ontario Building Code.

You usually need a permit if the work affects your home’s structure, size, or safety. That includes changing walls or cutting new openings.

Skipping a permit can cause problems. The city might issue a stop-work order. Insurance may not cover damage. And when you try to sell your home, the buyer’s inspector might flag unapproved work.

When You Do Not Need a Permit

Not all window replacements need a permit. If you are keeping things the same, you are usually fine.

You do not need a permit if:

• You are replacing a window with one of the same size.
• You are not changing the shape or location.
• You are not touching the structure around the window.
• You are only updating the frame, glass, or hardware.

For example, say you have a double hung window and you replace it with a new double hung window of the same size. There is no change to the wall or frame. In this case, no permit is required.

This type of work is considered a basic upgrade. It does not affect the building’s structure.

When You Do Need a Permit

Some window projects do need a permit. These involve bigger changes to your home.

You will need a permit if:

• You are increasing or decreasing the window size
• You are changing the shape or position
• You are cutting into a wall to add a new window
• You are changing a window into a door
• You are cutting into a load bearing wall
• You are installing or enlarging basement windows for emergency escape

These changes affect how your home functions or how safe it is. The city needs to approve them before the work begins.

Special Note About Basement Windows and Egress

Basement renovations are common in Toronto. People often add bedrooms or create rental units.

If you are adding a bedroom in the basement, the law requires a safe way to exit. This is called egress.

A basement window can count as an egress if it meets certain rules. These rules include:

• The opening must be at least 0.35 square meters.
• It must open without tools or keys.
• It must open wide enough for someone to climb out.
• There must be enough space outside for someone to escape.

To meet these rules, you may need to enlarge the window or dig a window well. This type of work always needs a permit.

What Is the Process to Get a Permit?

Permits are handled by Toronto Building, which is part of the City of Toronto.

Here is how the process works:

1. Drawings

You need basic plans showing what will be changed. For big changes, you may need help from an architect or engineer.

2. Application

Submit your forms online or at a city office.

3. Fees

You will pay a fee based on the type of work. It is often a few hundred dollars.

4. Review

The city checks that your plan follows building codes. They may ask for changes.

5. Approval

Once approved, you can start work. You may need inspections during or after the job.

The whole process usually takes two to four weeks.

What Happens if You Skip the Permit?

If you do work without a needed permit, the risks are serious.

You could be fined by the city. A building inspector could stop your project. Your home insurance may not cover damage related to the work. And when you try to sell your house, you may be forced to fix or remove the unapproved changes.

Fixing these problems after the fact is often more expensive and stressful than doing it right from the start.
