Zhiibaahaasing (or Cockburn Island First Nation) is a First Nation in the Canadian province of Ontario.
An Odawa and Ojibwe community located in the Manitoulin District, the First Nation has two distinct parcels of land: the first, on Manitoulin Island and legally designated as Zhiibaahaasing 19A, had a population of 34 in the 2001 Canadian census, and the second, located on Cockburn Island and legally designated as Zhiibaahaasing 19, had no permanent population in the same census.
There has been a significant amount of controversy surrounding a stockpile of more than one million tires within the Zhiibaahaasing First Nation. Cockburn Island Tire Recycling plans to process the tires, but due to an equipment malfunction, the facility is not currently operating. Many area residents are concerned about the health and environmental consequences should there be a fire. In September, 2006, Indian and Northern Affairs Canada agreed to provide funding for the removal of the tires.
