In German Canadians: Community Formation, Transformation and Contribution to Canadian Life, Grenke explores important themes in the German Canadian experience, including immigration, social life, the war experiences, intermarriage, political participation and the German contribution to Canadian life. Focusing on language maintenance and transition, the study explores their effect on the formation and decline of different German Canadian communities as they emerged and dissolved. While the reader may, or may not, agree with some of the conclusions reached, the work should, nevertheless, stimulate reflection and discussion.
