Documents the ecological importance of the UNESCO Frontenac Arch Biosphere Reserve — the wildlife corridor that the proposed southern route would bisect.

An immersive aerial view of the Rideau Canal — a UNESCO World Heritage Site and Canadian National Historic Site running through the proposed corridor area.

QUBS has decades of biodiversity research within the Frontenac Arch. Their long-term ecological data directly underpins the case for the biosphere’s international significance.

Two examples of flooding near the crossing of MacGillivray Road and the Cataraqui Trail. The confluence of the creek from Hinge Lake and the Cataraqui Trail railway ditch creates a frequent flood zone, with major washouts in 1986, 2002, 2013, and 2019. Water flows onward to Stonehouse Lake, Opinicon Lake, and the Rideau Canal. These are waterways, not ditches.
