In Canada, simply adding a basic digital colour filter to a public domain historical photo does not automatically grant you a new copyright. To legally own a “derivative work,” you must apply original “skill and judgment” during the restoration and colourisation process. Registering a valid new work with CIPO costs $63 CAD online.
Historical archives, such as Library and Archives Canada, are incredible resources for artists, historians, and content creators living in Ottawa, Montreal, and Winnipeg. Discovering a black-and-white photograph of the Canadian Pacific Railway from 1895 and bringing it to life with vibrant, modern colours is a fascinating project. However, many digital artists wonder: if the original image belongs to the public domain, who legally owns the newly colourised version?
Canadian copyright law treats derivative works differently than American law. We do not use the “sweat of the brow” doctrine; just because you worked hard on a photo does not automatically mean you own it. The law requires a specific threshold of original creativity. This guide breaks down the precise step-by-step process of determining copyright eligibility for restored historical photos, understanding the legal tests, and knowing when to retain a Canadian IP lawyer to protect your digital portfolio. 📍
Step-by-Step Process for Establishing Copyright on Colourised Photos
To successfully claim copyright over a colourised historical photograph in Canada, you must prove that your new version is not just a mechanical reproduction, but a brand-new artistic expression.
Step 1: Confirm the Original is in the Public Domain
Before you begin any commercial project, you must ensure the underlying black-and-white photograph is actually in the public domain. In Canada, as of recent changes to the Copyright Act, the general rule is that copyright lasts for the life of the author plus 70 years following the end of the calendar year of their death (up from the previous 50 years). If the photographer died more than 70 years ago, the image is free for anyone to use, modify, or sell without permission. 🔍
Step 2: Understand the “Skill and Judgment” Standard
In a landmark Supreme Court of Canada decision (CCH Canadian Ltd. v. Law Society of Upper Canada), the court ruled that an original work must originate from an author and must be the product of an exercise of “skill and judgment.” This means your colourisation process cannot be a purely mechanical exercise. Simply clicking a one-touch “auto-colourise” button in Photoshop or using an AI filter does not involve enough human skill and judgment to qualify for a new Canadian copyright.
Step 3: Apply Original Artistic Choices
To cross the legal threshold into creating a protectable derivative work, you must make deliberate, creative choices. This involves painstaking historical research to choose the historically accurate colours of a military uniform, manually repairing scratches and dust, adjusting contrast, and painting light and shadow by hand. When your specific choices give the photograph a unique artistic character that another artist would not have instinctively replicated, you have likely created a legally protectable work. 🖌️
Step 4: Document Your Creative Process
If someone ever steals your colourised image and you must sue them in the Federal Court, the burden of proof is on you. Therefore, you must rigorously document your digital workflow. Save your Photoshop project files (.PSD) with all the individual colour layers intact, keep a log of your historical colour research, and maintain time-stamps of your work. This undeniable evidence proves to a judge that the final image is a direct result of your human skill.
Step 5: Register the Derivative Work with CIPO
Once your detailed restoration and colourisation is complete, you should officially register the derivative work with the Canadian Intellectual Property Office (CIPO). On the application, you must clearly specify that your copyright claim is strictly for the “colourisation and digital restoration,” and not a claim over the original underlying public domain image. 🔒
How Much Does it Cost in Canada?
Protecting a digital portfolio of historical restorations is relatively inexpensive in Canada, provided you do not end up in complex litigation. Below are the typical costs as of May 2026.
| Service / Legal Task | Estimated Cost (CAD) |
|---|---|
| High-Res Archival Scans (Museums) | $15 – $50 per image |
| CIPO Copyright Registration (Online) | $63 per registration |
| IP Lawyer (Consultation on Validity) | $300 – $600 per hour |
| Drafting a Cease & Desist Letter | $500 – $1,500 |
How Long Does the Process Take?
Confirming the public domain status of a historical photograph can usually be done in a matter of days by checking provincial or federal archives. The actual human process of applying skill and judgment to restore a damaged photo can take anywhere from 10 to 50 hours of digital painting. Once you submit your online application to CIPO, the official copyright registration certificate is generally mailed to you within 1 to 2 weeks. ⏳
Frequently Asked Questions (FAQ)
If I use AI to colourise the photo, do I own it?
Generally, no. Canadian copyright law currently requires a human author. If a machine learning algorithm makes all the colour choices automatically without your direct creative input, the resulting image lacks the necessary human “skill and judgment” to be copyrighted.
Can someone else colourise the exact same original photo?
Yes, absolutely. Because the original photo is in the public domain, anyone can download it and create their own colourised version. You only own the copyright to your specific, uniquely coloured expression, not a monopoly on the image itself.
What if I colourise a photo that is not in the public domain?
If the original photographer is still alive, or died less than 70 years ago, creating a colourised version without their explicit permission is a direct infringement of their copyright. They can legally force you to destroy the work and demand financial damages.
Does copyrighting it prevent others from sharing it?
Yes, if you hold a valid copyright on the derivative work, others cannot legally print, sell, or commercially display your specific colourised version without purchasing a licence from you or falling under “fair dealing” exceptions (like news reporting or education).
Do I have to register with CIPO to be protected?
No, copyright in Canada is automatic upon the creation of the original work. However, registering with CIPO is highly recommended because it acts as a powerful legal presumption of ownership in the Federal Court if you ever need to sue an infringer.
