Partnering with Ottawa based Windmill Development group, the Zibi project involved remediation of more than 100,000 tonnes of contaminated soil on the islands around Chaudière Falls on the Ottawa River. The remediation formed part of the city’s brownfields rehabilitation grant and development charge reduction programs, which offer incentives to encourage redevelopment of post-industrial and heritage properties. This project engaged with the Algonquin-Anishinabe community to create training and development opportunities among its members within the construction industry.
