What Is the Test for Authentication of Electronic Documents?

Ali Lalji got involved in a cocaine smuggling conspiracy during the time he worked at Vice Media where he made friends with Yaroslav Pastukhov. They used the company’s headquarters in Toronto, Canada, to recruit couriers for the operation. But the plot may now be less remembered for its notoriety than the audio recordings made of it.

1. Introduction

On April 8, 2026, the Ontario Court of Appeal released the ruling in R. v. Lalji affirming the conviction of Mr. Lalji for conspiracy to import cocaine into Australia and dismissing his appeal from a nine year sentence imposed by Justice Russell Silverstein of the Ontario Court of Justice on January 27, 2023. (here) More than seven years after his arrest, the notorious case that revealed the use of Vice Media headquarters in Toronto to recruit interns, models and musicians as drug couriers has come to a close. Writing for the National Post, journalist Adrian Humphreys said the five couriers and Mr. Pastukhov, a former Vice Media editor, spent years behind bars in Ontario while Mr. Lalji remained free “courtesy of a keen legal strategy and logistical delays.” (here)

2. Background

On December 22, 2015, five travelers landed in Sydney, Australia on a flight from the United States. They were arrested and their cell phones seized when border authorities found 40 kilos of cocaine in their luggage. On January 31, 2019, Canadian authorities arrested Mr. Lalji and Mr. Pastukhov. Mr. Pastukhov pleaded guilty and turned state’s evidence at Mr. Lalji’s trial. Justice Silverstein found Mr. Pastukhov wanting for credibility but nonetheless convicted Mr. Lalji based mainly on the data extracted from the cell phones including electronic communications between Mr. Lalji and two of the couriers.

Robert Wang and his companion, Porscha Wade, were two of the couriers arrested in Sydney. The data extracted from their phones included: (a) text messages exchanged with Mr. Pastukhov during the days leading up to the trip and a phone number registered to Mr. Lalji; (b) WhatsApp messages exchanged in a group chat that included an account in Mr. Lalji’s name associated with the same phone number; and, (c) an email from an account in Mr. Lalji’s name that Mr. Pastukhov forwarded to Mr. Wang. The data also included two audio recorded conversations. I will focus on the audio recordings for purposes of this post because it was argued on appeal that the Crown failed to establish their authenticity.

3. Audio Recordings

The first recording had a date and time stamp indicating it was created on the evening of November 30, 2015. Mr. Pastukhov identified his own voice and that of Mr. Wang. He testified that their conversation “definitely happened at my apartment” but he claimed to be unable to remember anything else about the conversation including the identity of a third man who participated in the conversation. The second recording had a date and time stamp indicating it was created on the evening of December 14, 2015. It captured another conversation between Mr. Pastukhov, Mr. Wang and at least one other man and a woman. Mr. Pastukhov said the other male might have been a man named “Pope” who traveled to Australia with Mr. Pastukhov a few weeks earlier.

During the conversations, Mr. Pastukhov discussed steps that would be taken to avoid detection at the border. He told Mr. Wang the trip was organized by “guys from B.C.” working with “the Mexican cartel in Vegas”. Mr. Wang and Ms. Wade would each be given two suitcases to replace the luggage they brought with them. They would have to buy enough clothing in Las Vegas to fill both suitcases. Mr. Pastukhov also instructed Mr. Wang to use cigarettes to mask any smell in the suitcases and to buy ribbons or stickers “[s]o it looks like you travel with the suitcase all the time”. Mr. Pastukhov said there would be “other people doing this” on the same flight, one of whom was Mr. Pastukhov’s roommate, but “if you see anyone on the plane that you recognize, you don’t know them.”

4. Ruling on Admissibility

Mr. Lalji advanced two main arguments on the appeal. First, it was never established that the date and time stamps on the digital files were accurate and that “[w]ithout situating the recordings in time proximate to the alleged charge, the recording itself loses all probative value.” Second, the Crown failed to establish that the recordings had not been manipulated or altered because it did not adduce any “direct evidence” about how the recordings were made, who made them, or how they ended up on Mr. Wang’s phone.

Writing for the unanimous panel, Justice Jonathan Dawe began the analysis with references to the Canada Evidence Act and the opinion of Justice David Watt in R. v. C.B. (here and here) Under s. 31.1 of the Act, the Crown had to establish the authenticity of the recordings “by evidence capable of supporting a finding that the electronic document is that which it is purported to be”. Justice Dawe held that the expansive definition of “electronic document” in s. 31.8 includes digital audio recordings. The authenticity threshold, however, is low. In C.B., Justice Watt described it as a “modest threshold” whether at common law or under s. 31.1 of the Act. “Section 31.1 does not limit how or by what means the threshold may be met,” he said. “Its only requirement is that the evidence be capable of supporting a finding that the electronic document ‘is that which it is purported to be’.”

Justice Dawe agreed that the digital date and time stamps could not be “blindly assumed” to be accurate. However, this did not automatically make the recordings themselves inadmissible. “Documents, whether physical or electronic, may be received into evidence even when their creation date is entirely unknown,” Justice Dawe said. “Whether or how much this affects their probative value in a particular case is for the trier of fact to determine.” In this case, since the trial judge found the conversations on the two audio recordings to be admissible for their truth under the co-conspirators’ exception to the hearsay rule, he was entitled to rely on the substance of the conversations to draw inferences about when they took place, by situating the recordings in the context of the electronic communications retrieved from the couriers’ seized phones.

Justice Dawe disagreed that “direct evidence” was essential to establish that the recordings had not been manipulated. Under s. 31.1 of the Act, the modest threshold for authentication may be established circumstantially. Here, the circumstances in which the recordings were retrieved supported the inference that they were unlikely to have been altered. For instance, contemporaneous text messages exchanged between Mr. Pastukhov and Mr. Wang about plans to meet, apparently to discuss the scheme, aligned with the time when the first recording was apparently made. On the second recording, Mr. Pastukhov told Mr. Wang they would set up a WhatsApp group chat “with the four of us. You, me, Porscha and Ali.” The WhatsApp group with these four participants was then created that same night.

5. Conclusion

I will leave you, then, with this question. What is the test for authentication of electronic documents? I will answer it by giving you Justice David Paciocco’s article published in the Canadian Journal of Law and Technology in 2013 titled Proof and Progress: Coping with the Law of Evidence in a Technological Age. (here) Section 31.1 of the Act does nothing more than repeat the “low” common law authenticity standard. “At common law authenticity is established for the purposes of admissibility if the trial judge is satisfied that there is some evidence to support the conclusion that the thing is what the party presenting it claims it to be,” Justice Paciocco said. In R. v. Donald, the New Brunswick Court of Appeal held that positive identification is not required. (here) “The fact an article has been admitted in evidence does not, of course, establish that it is the article involved. After its reception it is a question of fact to be determined by the judge or jury as to whether or not it is, in fact such article.” Section 31.1 of the Act contains the same test.
