A2AJ加拿大案例法数据集提供了加拿大法院和法庭的批量、开放获取的全文裁决。每一行对应一个案例，包含公开可用的英文和法文版本的裁决。该项目基于之前由难民法律实验室（RLL）维护的版本，现由约克大学Osgoode Hall法学院和多伦多都会大学Lincoln Alexander法学院共同主持的研究项目A2AJ维护。数据集旨在支持实证法律研究、法律技术原型设计以及语言模型预训练，尤其关注促进边缘化和低收入社区的司法公正。数据集包含约118k案例，涵盖多个法院和法庭的裁决，时间跨度从19世纪至今。数据字段包括法院/法庭缩写、引用、案件名称、裁决日期、来源URL、抓取时间戳、非官方文本全文以及上游许可证。数据集还考虑了隐私风险和社会影响，鼓励下游用户与社区组织合作，确保衍生工具促进而非削弱司法公正。

The A2AJ Canadian Case Law dataset provides bulk, open-access full-text decisions from Canadian courts and tribunals. Each row corresponds to a single case and contains the English and French versions of the decision where both are publicly available. The project builds on an earlier version that was maintained by the Refugee Law Lab (RLL) and is now maintained by A2AJ, a research project co-hosted by York Universitys Osgoode Hall Law School and Toronto Metropolitan Universitys Lincoln Alexander School of Law. The dataset is intended to support empirical legal research, legal-tech prototyping, and language-model pre-training in the public interest—especially work that advances access to justice for marginalised and low-income communities. The dataset includes approximately 118k cases from various courts and tribunals, spanning from the 19th century to the present. Data fields include court/tribunal abbreviations, citations, case names, decision dates, source URLs, scraping timestamps, unofficial full texts, and upstream licenses. The dataset also addresses privacy risks and social impact, encouraging downstream users to collaborate with community organizations to ensure derivative tools advance rather than undermine access to justice.
