1844 - 1885 CE
David Louis Riel attempts to curbe the whisky trade, but does not succeed.

David Louis Riel, who was recognized as one of Canada's founding fathers, spent some of his life working as a trader. This resulted in his opposition to alcohol. Observing rampant alcoholism and its detrimental impact on Native American and Métis people, he engaged in an unsuccessful attempt to curtail the whisky trade when he lived in the United States (Montana). Many people were benefitting economically from the whisky trade, so his efforts failed.
