Water ambassadors Canada has participated in the Scotiabank Waterfront Marathon for the past 4 years. In that time we have raised about 50 thousand dollars. We are trying to get the word out about the desperate need for clean drinking water in the Developing world. Women and children carry heavy buckets of water for their families. The water is usually contaminated. To demonstrate this, Water Ambassadors volunteers try to carry empty buckets the 5 km distance.
