The Canadian Tax Foundation, as part of its mandate to provide support for research, analysis, and informed commentary on Canadian public finance, has partnered with a group of academic researchers to launch the Finances of the Nation project. This open-access website assembles data on Canadian public finance (essential information about government revenue and expenditure, statutory tax rates, and the specific costs and benefits of particular taxes and spending programs), along with the Foundation’s Finances of the Nation journal features, with a view to supporting the analysis of taxation and public spending in Canada. The website’s datasets and cutting-edge tools make the wide-ranging collection useful to researchers, journalists, students, and the general public. The project aims not only to improve general access to critical information but also to promote research by expanding the network of Canadian scholars and stimulating the cross-sector engagement of researchers, tax professionals, and policy makers.
