加拿大惟一陆地接壤的邻国是美国,其在加美边境没有军队布防,数量不多的空军也由美国指挥。因此,其紧急救援机构主要是针对非战争情况下的突发事件开展工作,其地下工程设施也不考虑防空问题。
The only neighbor bordering Canada is the United States, with no troops on the border with the United States and a small number of air forces under the command of the United States. Therefore, its emergency aid agencies mainly work on emergencies in non-war situations and the underground engineering facilities do not consider air defense issues.
