No country is more blessed with fresh water than Canada. MacGregor, has paddled, sailed and traversed Canada's rivers, learned their stories and secrets, and the tales of centuries lived on their rapids and riverbanks. He raises lost tales, like that of the Great Tax Revolt of the Gatineau River, and reconsiders histories like that of the Irish would-be settlers who died on Grosse Ile and the incredible resilience of settlers in the Red River Valley. Along the Grand, the Ottawa and others, he meets the successful conservationists behind the resuscitation of polluted wetlands, including even Toronto's Don, the most abused river in Canada (where he witnesses families of mink, returned to play on its banks). Long before our national railroad was built, our rivers held Canada together; in these sixteen portraits, filled with yesterday's adventures and tomorrow's promise, MacGregor weaves together a story of Canada and its ongoing relationship with its most precious resource. 2017.
