My choice is the Last Spike of the Canadian Pacific Railway. The final spike was driven into the Canadian Pacific Railway at Craigellachie, British Columbia on November 7, 1885. This transcontinental railway united Canada from east to west, and it was the promise of this that lured B.C. into joining Confederation. Also, thousands of Chinese and other immigrants arrived in Canada to aid in the building of the most difficult and dangerous sections. Though these workers faced overt racism, those who survived and stayed have contributed to the multicultural character of Canada.
