The United States' northern neighbor was indignant regarding the assassination of Abraham Lincoln, considering it to be "the greatest crime of our age, as committed not merely against the people of the United States, but against our common humanity and common christian civilization." Such impassioned language and statements were not limited to Canada, though Canada and the United States' relationship has traditionally been one of friendship and mutual cooperation, contributing to the country's powerful statement of support for the United States in 1865.

In 2015, time has decreased the amount of anger and sadness felt regarding the passing of Lincoln, as time separates us from his immediate presence. However, an understanding of Lincoln's importance in history grows with each passing year as the legacy of his far-reaching achievements is better understood by historians and other citizens. Louise Guillemette-Labory's letter matching that of 1865 draws a comparison between Lincoln's vision of a country marked by inclusion and equality and the ways that the city of Montreal has worked to extend these values into its own social organizations.
