arXiv:2605.30497v1 Announce Type: new Abstract: RAG-based legal assistants have been growing in popularity, but LLM hallucinations remain a key issue and potentially undermines justice. While benchmarks have been developed to evaluate progress, many rely on synthetic queries rather than realistic legal scenarios. Moreover, Canadian law remains underrepresented in existing evaluations. To address this gap, we introduce CanLegalRAGBench, a Canadian legal QA benchmark based on realistic queries and expert-annotated answers grounded in case law. Our evaluation shows that retrieval performance is s
The proliferation of LLMs and their application in specialized domains like law necessitates robust evaluation benchmarks to address issues like hallucination, especially as legal systems are highly sensitive to accuracy.
Accurate, ethical, and regionally specific AI legal tools are crucial for maintaining the integrity of justice systems and fostering public trust in AI applications.
The introduction of CanLegalRAGBench provides a specialized, realistic benchmark for evaluating Retrieval-Augmented Generation (RAG) legal AI in a Canadian context, potentially improving the reliability and adoption of these systems.

This benchmark will enable more reliable and trusted AI-powered legal assistants in Canada.
Improved AI legal tools could enhance access to justice and legal efficiency by reducing research times and potentially legal costs.
The success of region-specific legal AI benchmarks could spur similar localized initiatives globally, leading to a fragmented but highly specialized legal AI landscape.
