The parkways, avenues, and trails in OTtawa all follow these waterways, but there are no real destinations to actually stop and enjoy these places (waterfront bistros, bars, cafes, playgrounds, waterparks, basketball/tennis courts, buskers, etc..) - except sort of at Lansdowne.
Even a plaza next to the canal or river would be nice. Pavers, seating, shade, flowers, perhaps even music playing on outdoor speakers. Something like the Chicago Riverwalk.. You wouldn't know Ottawa is a waterfront city because the city doesn't embrace it.
