How Long Should a Business Keep Security Camera Footage in Ontario?

It’s one of the most common questions we get from business owners after a camera install: how long do I actually need to keep the footage? The short answer is that there’s no single number written into Ontario law for most private businesses — but that doesn’t mean the decision is arbitrary. The right retention window depends on your industry, your risks, and a few practical realities about storage. Here’s how to think about it.

There’s No One-Size-Fits-All Legal Number

For most private commercial businesses in Ontario, the law doesn’t mandate an exact number of days to retain security footage. Privacy legislation focuses more on how you collect and handle recordings — reasonable purpose, appropriate signage, not over-collecting — than on a fixed retention period. That said, some regulated industries and specific situations (certain licensed premises, insurance requirements, or contractual obligations) do come with their own expectations, so it’s worth checking whether anything specific applies to your sector.

What Actually Determines the Right Window

In practice, most businesses land somewhere between 30 and 90 days. Here’s what pushes that number up or down:

• How long incidents take to surface. A break-in is obvious the next morning. But internal theft, a slip-and-fall claim, or a dispute might not come to light for weeks — which is why many businesses keep at least 30 days, and cautious ones keep 60 to 90.
• Insurance and liability. Some insurers or claim processes expect footage to be available for a certain period. If a claim can arrive 30 or 60 days after an event, your retention needs to outlast that.
• Your industry’s risk profile. A retail store, a bar, and a warehouse all have different exposure. Higher-risk or higher-traffic sites often justify longer retention.
• Number of cameras and resolution. More cameras and higher resolution eat storage faster — which directly affects how many days you can hold at the quality you want.

Retention Is a Storage Decision, Not Just a Setting

Here’s the part that catches businesses out: your retention window is only real if your storage can actually hold it. A system recording ten high-resolution cameras 24/7 fills up far faster than one recording four. If the storage is undersized, the recorder simply overwrites the oldest footage early — so you think you have 60 days but really have 18, and you find out at the worst possible moment. Getting retention right means sizing the recorder and drives around your actual camera count, resolution, and frame rate, so the window you’re counting on is the window you actually have.

Make Sure the Footage Is Usable When You Need It

Keeping footage is only half of it — being able to find and export it matters just as much. A well-set-up system lets you quickly locate the right camera and time, and export a clip for police or an insurer without wrestling the whole system. It’s also worth protecting critical footage so an incident recording doesn’t get overwritten before someone retrieves it. When we design a system, we set retention, storage, and access up together so the footage is there, and usable, when it counts.

Not Sure What’s Right for Your Business?

The right answer depends on your space, your cameras, and your risks — and it’s easier to get right at install time than to fix later. We design and install commercial security systems in Ottawa with retention and storage sized to how your business actually operates, so you’re not guessing.
