战后初期，英国与加拿大传统关系趋于瓦解，两国全面“脱钩”，仅存依靠彼此情感需求维系的传统亲密关系。1956年，处于风雨飘摇中的英加传统关系又遭苏伊士运河危机的沉重打击。危机中，两国的应对方案存在分歧：英国决意不惜一切手段维护它在运河区的利益；加拿大虽然同情并愿意帮助英国，也经历了从游离到积极参与的转变，但它坚持主张由相关大国在联合国框架下达成一致来解决危机。英国的一意孤行招致加拿大不满，加拿大一直未曾提供英国真正想要的帮助也引起英国怨愤；两国由在危机外交解决阶段的不和，最终走向英国诉诸武力后的公开对立。由此，继全面“脱钩”之后，两国的传统亲密关系又遭致命冲击。运河危机中英加的互动宣告了两国传统关系的终结，标志着两国完成了对帝国传统纽带的超越。苏伊士运河危机成为英加传统关系瓦解与超越的转折点。
In the early postwar period，the traditional Anglo-Canadian relationship was in the process of loosening，and they had been completely separated in terms of security，economy and politics. Although the traditional intimate relationship between Britain and Canada still existed，it was only based on each other’s emotional needs. 1956，the traditional relationship between the two countries was hit hard by the Suez Crisis. During the crisis，there were differences in their solutions：Britain spared no efforts to safeguard its interests in the canal zone，and finally resorted to force；although Canada sympathized with and always claimed to be willing to help Britain，and experienced a transition from alienation to active participation，it insisted that the major powers concerned should reach an agreement under the framework of the United Nations. Britain’s obstinacy caused dissatisfaction with Canada，and Canada’s failure to provide the help that Britain really wanted also caused resentment from Britain. The disagreement between them in the diplomatic settlement stage of the crisis finally turned into an open opposition after the British invasion of Egypt. Thus，the traditional intimate relationship suffered a fatal impact，and the interaction between Britain and Canada in the Suez Crisis announced the end of their traditional bilateral relationship and the transcendence of the traditional ties of the empire. Suez Crisis become a turning point of the disintegration and transcendence of the traditional relationship between Britain and Canada.
