The location of Montreal and Ottawa in the active Western Quebec seismic zone places them at risk of seismic hazards. The potential risk was recently highlighted with the magnitude M5.0 earthquake on June 23, 2010, located about 50 km northeast of the city of Ottawa. This earthquake was felt strongly in areas of Ottawa that are located on soft postglacial sediments, which amplified the level of earthquake shaking. Soil amplification can significantly influence the ground motions and hazards of seismic events; and, the most recent version of the National Building Code of Canada (2005) recognizes its importance with a seismic site classification system to determine soil amplification factors.

蒙特利尔和渥太华位于活跃的西魁北克地震带，使它们处于地震危险的危险之中。2010年6月23日，位于渥太华市东北约50公里处的5.0级地震突出了潜在的风险。这场地震在渥太华地区有强烈的感觉，这些地区位于冰川后的软沉积物上，这放大了地震震动的程度。土壤放大作用可以显著影响地震事件的地面运动和危害;并且，最新版本的加拿大国家建筑规范（2005年）认识到其重要性，并通过地震场地分类系统确定土壤放大系数。
