The greatest impact on Canada was as a result of World War II due to Canada's extensive effort in this war as opposed to World War I.
Spain had the greatest impact on Latin America.
It is probably impossible to argue what had the greatest impact on world history, it did of course have a massive impact and we still see its legacy now, but there are other things that have had an impact that is still with us (from the Roman Empire through to the Cold War). I think this probably counts as either a question that cannot be answered, or one that should be answered simply as "No".
