As lawyers increasingly use AI in their practice, we see more cases where courts deal with legal submissions involving AI hallucinations. This case deals with the issue of AI hallucinations and the failure to advise the court of the use of AI.

In Wael Mostafa Aly Hussein et al. v. The Minister of Immigration, Refugees and Citizenship (2025 FC 1060), the Federal Court of Canada scrutinized the undeclared use of generative artificial intelligence (GenAI) in legal submissions made by Applicants' counsel in a motion to admit new evidence and request for an extension of time to file the Applicant Record.

After the Court could not locate a few authorities referenced in the Applicants' materials, it issued several Directions requiring a Book of Authorities. It was only after the last Direction was issued that Applicants' counsel advised of his reliance on Visto.ai, an AI legal research tool designed specifically for Canadian immigration and refugee law practitioners.

Canada Commits To Airport Privatization Through Long-Term Concessions For Its Four Largest Airports

The Canadian federal government has announced a firm commitment to privatize operations at the country's four largest airports through long-term concessions, marking a decisive shift from earlier exploratory discussions.
