Final answer:
Canadian sovereignty has developed since 1914 through events such as World War I and the Quebec separatist movement. The cultural and ethnic makeup of Canada has also been influenced by immigrants.
Step-by-step explanation:
Canadian sovereignty has developed since 1914 as a result of various events and factors. One major event that affected Canadian sovereignty was World War I, which led to increased independence and recognition for Canada on the international stage. The country's participation in the war and its sacrifices contributed to a sense of national pride and identity.
Another significant development was the separatist movement in Quebec during the late 20th century. While Quebec's bid for independence ultimately did not succeed, it sparked important discussions about the balance between provincial and federal power within Canadian governance.
Additionally, the cultural and ethnic makeup of Canada has been shaped by the influx of immigrants. The country's policy of multiculturalism has welcomed diverse groups, leading to a more inclusive society and impacting Canadian sovereignty by promoting social cohesion and understanding.
