The National Capital Commission is warning pedestrians and cyclists to be careful on paths because recent high water levels have damaged and closed several parts of the Capital Pathway network.

"Of our 250 kilometres of pathways, which make up almost half of the pathway system in the capital region, there's a good portion of them that went underwater, were damaged, and will need remediation," NCC CEO Mark Kristmanson told CBC Radio's Ottawa Morning Friday.

"We documented, extensively, the flooding, so that we know exactly how the assets were affected, and where possible, we'll shift to higher ground or increase resiliency.

"But I would say that the general policy and direction set by Sir Wilfrid Laurier over 100 years ago — it was a really good idea — acquire the shorelines into the public realm and turn them into public spaces, because in a sense they are resilient. We can restore pathways easier than we can restore people's houses and buildings and so forth.

"We'll look back and we'll replace them in as smart a way as we can."

Several paths are still closed due to flooding, though part of the Ottawa River Pathway between Pioneer Road and the Rideau Canal reopened Thursday afternoon.
