This dataset provides projected 30-year, 50-year, and 100-year return levels for harbours in British Columbia by 2050 and 2100 under an intermediate emission scenario SSP245, relative to the mean sea level over 1993-2020. The return levels are a combination of estimated present extreme sea levels and projected mean sea level rise. The present extreme sea levels are derived from hourly coastal sea levels for the period from 1993 to 2020, simulated using a high-resolution Northeast Pacific Ocean Model (NEPOM). The projected mean sea level rise is derived from the regional mean sea level rise data of the IPCC 6th Assessment Report under SSP245, adjusted for the local vertical land motion.

This dataset provides projected sea surface temperature and salinity as well as projected ocean bottom temperature and salinity in the Northwest Atlantic under an intermediate emission scenario Representative Concentration Pathway (RCP) 4.5. The results are generated by a North Atlantic Ocean-ice Downscaling System (NAODS) that downscales the global Hedley Centre Global Environmental Model Version 2 with an Earth System component (HadGEM2-ES) output. NAODS couples a 1/12 ^o model for the northwest Atlantic with a 1/4 ^o model for the North Atlantic (Han et al., 2025). Bi-decadal means are included for 1986-2005, 2006-2025, 2026-2045, 2046-2065, 2066-2085, and 2080-2099, respectively.

This is a magnitude 5.0 earthquake scenario under Lake Ontario, very close to Toronto. This fault is not known to be active but demonstrates a plausible earthquake scenario for Toronto region.

A magnitude 5.6 rupture scenario near Ottawa along the Gloucester Fault in the south of the city. This fault is not known to be active, but this scenario is representative of seismicity in the Ottawa Valley.

This dataset provides projected sea surface temperature and salinity as well as projected ocean bottom temperature and salinity in the Northwest Atlantic under a high emission scenario Representative Concentration Pathway (RCP) 8.5. The results are generated by a North Atlantic Ocean-ice Downsling System (NAODS) that downscales the global Climate Change System Model Version 4 (CCSM4) output. NAODS couples 1/12-degree model for the northwest Atlantic with a 1/4-degree model for the North Atlantic (Han et al., 2025). Bi-decadal means are included for 1986-2005, 2006-2025, 2026-2045, 2046-2065, 2066-2085, and 2080-2099, respectively.

Magnitude 5.7 earthquake scenario located directly southeast of Ladysmith Town Centre. This fault is not known to be active, but this scenario represents a small but damaging event near Ladysmith and Burleith Arm.

Magnitude 5.5 earthquake scenario located directly southeast of Ladysmith Town Centre. This fault is not known to be active, but this scenario represents a small but damaging event near Ladysmith and Burleith Arm.

This dataset contain the 1:20,000 scale contour elevation text converted from the Provincial Digital Base Mapping Project. These contours require the use of elevation text to properly interpret the elevation value of a specific contour. There are two major types of contours, index contours and intermediate contours. Index contours are identified every 5th contour line. For Alberta, the index contour intervals occur every 50 metres in relatively flat terrain and every 100 metres in mountainous terrain. Intermediate contours are contour lines that occur between the index contours. For Alberta, the intermediate contour intervals are every 10 metres in relatively flat terrain and every 20 metres in mountainous terrain. Where elevation change is sudden, intermediate contours may be deleted and only index contours are shown. The elevation text is associated with the index contours. Currently, no contour information exists for Banff, Jasper and Wood Buffalo National Parks and also for the extreme north east portion of the province. See the Completeness Report in this metadata record for details regarding coverage.

This is a magnitude 5.0 earthquake scenario along the Burlington Toronto Structural Zone — a fault near Toronto and its surrounding region. This fault is not known to be active but demonstrates a plausible earthquake scenario for the Toronto region.

This dataset contains all of the 1:20 000 scale contour information converted from the Provincial Digital Base Mapping Project. These contour arcs are a cartographic product and they do not have any elevation values attributed to the spatial features. These contours require the use of elevation text to properly interpret the elevation value of a specific contour. There are two major types of contours, index contours and intermediate contours. Index contours are identified every 5th contour line. For Alberta, the index contour intervals occur every 50 metres in relatively flat terrain and every 100 metres in mountainous terrain. Intermediate contours are contour lines that occur between the index contours. For Alberta, the intermediate contour intervals are every 10 metres in relatively flat terrain and every 20 metres in mountainous terrain.
