Monday, June 26

Founder’s Reception
An event to recognize the founders of CLRA who have made outstanding contributions to rehabilitation within the mining and aggregate industries.

Day 2 – Tour Agenda

Tour option 1: Aggregate Tour (8:15 a.m. to 4 p.m.)
The Aggregate Tour will feature a tour of brownfield sites and aggregate sites within the Guelph area that have been rehabilitated to a variety of land uses.

Tour stops include:

• Eastview Pollinator Park, a former 45-ha. landfill site that is now home to pollinator habitat.

• Kelso Quarry Park, a rehabilitated quarry within the NEP and Greenbelt, that now contains a lake, beach, boardwalk, shoals for fish habitat and a trail network that connects to the Bruce Trail.

• A naturalized aggregate site which includes a rare fen plant community and is located just north of the Fletcher Creek Ecological Preserve.

• CBM’s McMillan Pit, a former pit converted to an aquaculture facility which is now home to thousands of rainbow trout.

• Capital Paving’s Wellington 5 Pit where the land was returned to agricultural use, and rehabilitation plans include a wildlife corridor.

• Guelph Metalworks, a Canadian Brownsfield Network award winner for reclamation of industrial lands.

Tour option 2: Mining Tour (8 a.m. to 5 p.m.)
The Mining Tour will include visits to the experimental plots near the city of Port Colborne Ont., the location of Vale Canada’s Ni refinery, which operated until the early 1980s, resulting in elevated soil Ni, Cu and Co concentrations in agricultural fields and woodlots. Remediation strategies being demonstrated on the agricultural fields include deep-till and liming at various rates. The tour will also stop at a woodlot on soil with very high Ni concentrations, for which remediation options are being considered. 

Visits to two other locations are also planned.
