The projections incorporate contributions to global sea-level from glaciers and ice sheets, warming of the oceans, groundwater extraction and impoundment of water in reservoirs. Differences in vertical land motion result in significant variability in relative sea-level projections across Canada. For the range of emissions scenarios, projections range from up to about one metre of sea-level rise by 2100 for localities in the Maritimes, to more than one metre of sea-level fall by 2100 for some sites in northern Canada. Additional sea-level rise could result from partial collapse of the West Antarctic ice sheet over this century. The projections of mean relative sea level described here give a basis for considering future extreme water levels and associated flooding events.
