Lt. Col. John By was the person put in charge of all major decisions regarding canal size, cost, labour, and organization; his ultimate control over the project, however, was very much limited by the financial resources allotted to him by his superiors. The British Treasury funded the construction of the Rideau Canal to secure colonial interests, but its Board of Ordnance kept a tight hold on the purse strings. By’s suggestions for improvements and extensions to existing plans were often dismissed outright for financial reasons; lengthy delays between correspondences also led to frequent misunderstandings and other costly mistakes. With each letter taking two months or longer to travel the necessary 5,000 km, not to mention the Board of Ordnance’s lengthy review process, By’s appeals would often arrive even as further restrictions were already in transit from London. By’s proposal for larger locks, for instance, was sent when orders to decrease the locks’ size were already en route back to Canada. When the Board of Ordnance finally approved larger locks, construction was already underway, and workers were forced to demolish the new masonry in order to begin again. The debate over the size of the locks stretched over more than a year because of these delays and miscommunications, much to the frustration of all involved.
