Multiple national scale framework data are available from Natural Resources Canada in the following portal: http://geogratis.gc.ca/api/en/nrcan-rncan/ess-sst/$categories?scheme=&q=GeoBase
The frequency of updates is uncertain, for examples roads may be updated more frequently than lets say political borders since they do not change, the same can be said for water features. An examination of the full metadata for the road network of the province of British Columbia indicates that it is updated annually http://geogratis.gc.ca/api/en/nrcan-rncan/ess-sst/0e497e59-b9d0-4794-aef9-59b52b448c2b.html
