The hydrographic features of the CanVec series include watercourses, water linear flow segments, hydrographic obstacles (falls, rapids, etc.), waterbodies (lakes, watercourses, etc.), permanent snow and ice features, water wells and springs. The Hydrographic features theme provides quality vector geospatial data (current, accurate, and consistent) of Canadian hydrographic phenomena. It aims to offer a geometric description and a set of basic attributes on hydrographic features that comply with international geomatics standards, seamlessly across Canada. The CanVec multiscale series is available as prepackaged downloadable files and by user-defined extent via a Geospatial data extraction tool.

CanVec contains more than 60 topographic features classes organized into 8 themes: Transport Features, Administrative Features, Hydro Features, Land Features, Manmade Features, Elevation Features, Resource Management Features and Toponymic Features. This multiscale product originates from the best available geospatial data sources covering Canadian territory. It offers quality topographic information in vector format complying with international geomatics standards. CanVec can be used in Web Map Services (WMS) and geographic information systems (GIS) applications and used to produce thematic maps. Because of its many attributes, CanVec allows for extensive spatial analysis.

The Ontario Watershed Boundaries (OWB) collection represents the authoritative watershed boundaries for Ontario. The data is based on a framework similar to the Atlas of Canada Fundamental Drainage Areas and the United States Watershed Boundary Dataset, however it adopts a more stringent scientific approach to watershed delineation. The Ontario Watershed Boundaries (OWB) collection includes five data classes:OWB Main (OWB) (Download: Shapefile | File Geodatabase | Open Data Service | QGIS Layer )all watershed levels from primary to quaternary, and level 5 and 6 watersheds for select areas of the province;OWB Primary (OWBPRIM) (Download: SHP | FGDB | ODS | QLR-Diverted Flow | QLR-Natural Flow)all primary watersheds or major drainage areas (WSCMDA) in the Canadian classification;OWB Secondary (OWBSEC) (Download: SHP | FGDB | ODS | QLR*)all secondary watersheds or sub drainage areas (WSCSDA);OWB Tertiary (OWBTERT) (Download: SHP | FGDB | ODS | QLR*)all tertiary watersheds or sub-sub drainage areas (WSCSSDA);OWB Quaternary (OWBQUAT) (Download: SHP | FGDB | ODS | QLR)all quaternary watersheds or 6-digit drainage areas (WSC6).*Display issues in QGIS are currently being investigated for these services.

Status Completed: Production of the data has been completed

Maintenance and Update Frequency Irregular: data is updated in intervals that are uneven in duration - usually after the completion of major updates to source data (e.g. OIH), but could also include spot updates and expansion of the dataset over time based on user needs.
