Each set is downloadable on its own, for the entire country. Updated as required. Some of the datasets are updated more frequently at the local level and those are produced by the provinces, terriroties and cities. Data use requires geomatics expertise and software. As the original submitter Tracey Lauriault notes: "these data were difficult to find. Also keep in mind that Provinces, Territories and cities also produce some of these data and these would be at different scales and would have different update schedules."

Thank you, Tracey Lauriault, for contributing to the Global Open Data Index.
