AI, Deepfakes: How Quebec Judges are Treating Tech-Generated Evidence in 2025

In recent years, artificial intelligence (“AI”) has advanced at an astonishing and exponential pace. This rapid growth is both fascinating and, frankly, a bit unsettling. Today, AI is increasingly relied upon by the public as a seemingly all-encompassing solution. People turn to tools like ChatGPT for everything from medical advice on symptoms to legal guidance on specific situations and even for relationship counseling. Some have even begun forming emotional connections with their AI companions. 

While ChatGPT and similar AI models are impressive, they are far from infallible. They often produce mistakes and should not be considered reliable sources for professional or critical advice. 

Although AI is not yet perfected, its current capabilities to create, modify, and manipulate images and videos are incredibly advanced, so much so that they can easily deceive the average viewer. Increasingly, as we scroll through social media feeds, we encounter AI-altered images and videos without even realizing it. This growing prevalence has led to widespread uncertainty about what to trust and believe. 

This raises important questions about the implications for the justice system. How will courts handle evidence that can be so convincingly fabricated or altered through AI? Could AI make it easier to frame someone, or conversely, to erase guilt by tampering with evidence? 

For example, a civil litigation lawyer might face situations where opposing evidence is questioned because of suspected AI tampering, creating new challenges in family and civil cases. 

Current Legal Framework on AI in Canada

At present, Canada does not have a comprehensive legal framework specifically addressing AI. Although Bill C-27 was introduced in 2022 and was under development in Parliament, the legislation stalled. On January 6, 2025, the bill was officially removed from the Order Paper following Prime Minister Justin Trudeau’s resignation and the prorogation of Parliament.

For now, clients often turn to established family law firms and civil lawyers in Montreal to understand how AI-related disputes may affect their cases, since there is still no unified Canadian AI law. 

Crafting effective legislation involves the input of multiple stakeholders and several rounds of revision to ensure alignment with societal needs and legal principles. As a result, the legislative process can be slow, often lagging behind technological advancements and the realities faced by society. Unfortunately, in the case of AI, Canada’s legal system has yet to catch up, leaving a significant gap in regulation and oversight.

Lawyers and the Use of AI in their Practice

Judges today are increasingly aware of the implications of AI in legal proceedings. In particular, courts have made it clear that lawyers must rely on credible and verifiable sources when presenting arguments. AI-generated content should not be used as a substitute for legislative texts or jurisprudence. In fact, the Quebec Court of Appeal has issued a formal notice cautioning lawyers against relying on AI tools for their legal arguments. It explicitly requires that all claims be supported by authoritative and reliable sources. 

This reflects the responsibility of every family lawyer in Montreal and family law attorney elsewhere to ensure that AI tools are never mistaken for legal precedent. 

That being said, AI remains a useful tool for assisting professionals with superficial tasks, thereby enhancing the overall effectiveness of their practice. 

Options When Suspecting the Use of AI-Altered Evidence

When it comes to evidence, it’s important to distinguish between the various types, as each is treated differently under the law. These include authentic acts, semi-authentic acts, private writings, and the production of real evidence, among others. 

If a party suspects that a piece of evidence may have been altered using AI or otherwise manipulated, there are legal mechanisms available to contest its authenticity. The concerned party may challenge the evidence and request that it be examined. Experts can be called upon to analyze the document or media in question and determine whether any alterations have occurred.   

In complex cross-border disputes, international family law specialists may also be required to assess whether evidence created in another jurisdiction meets Quebec or Canadian standards. 

Legal Consequences of Altering Evidence

Tampering with evidence, particularly with the intent to mislead, carries serious legal consequences. Under the Criminal Code, forging an authentic document, one issued by a competent public officer, is a criminal offense under Article 366. Likewise, fabricating evidence is a separate offense under Article 137.  

In addition to criminal sanctions, civil courts also have the authority to impose penalties for contempt of court. This includes behavior that interferes with the administration of justice, such as submitting falsified evidence.

Given these risks, individuals are encouraged to consult with a civil litigation lawyer or family law firm that has experience handling cases where digital or AI-generated material is presented as evidence.
