The Canadian Expeditionary Forces faced discrimination in different forms during World War I, including racial discrimination against African Americans, feelings of abandonment and loss of language rights among English Canadians, and transformative experiences for Canadian women.
Step-by-step explanation:
The Canadian Expeditionary Forces faced various types of discrimination during World War I. One example is the discrimination faced by African Americans, who were denied enlistment opportunities and had a higher rejection rate for draft exemptions compared to other men. Another example is the discrimination faced by English Canadians, who felt abandoned by their country of origin, France, and experienced the loss of French language rights in certain provinces and schools in Ontario. Canadian women's wartime experiences also brought significant changes to their lives.
