The Welland Canals Corridor, Then and Now is a unique study in photographs of the four Welland Canals. The authors have taken historic photos of the canals and locks, and matched them as closely as possible with modern views of the same areas. The modern colour photos, by Master Photographer Thies Bogner, illustrate the beauty of the canal lands and show their current impact on the landscape. Together, past and present views give us a clear picture of the changing importance of an international waterway and its effect on industry and local economies.
