The Road Network File (RNF), is the first official release from the 2006 Census Geography suite of products and services. The RNF is a digital representation of Canada"s national road network, containing information such as street name, type, direction and address ranges.

It is available for download in several formats, including Geography Markup Language (GML). This XML-based text format lends itself not only to use in commercial and open source GIS tools, but also to access using standard XML style sheets and tools for analysis, visualization and reporting. The GML standard leverages several modern internet standards and is a key component of the Canadian Geospatial Data Infrastructure (CGDI).
