The Inco Superstack in Sudbury, Ontario, with a height of 381 metres (1,250 ft), is the tallest chimney in Canada and the Western hemisphere, and the 2nd tallest freestanding chimney in the world after the GRES-2 Power Station in Kazakhstan. It's also the second tallest freestanding structure of any kind in Canada, behind the CN Tower but forward of First Canadian Place. It's the 40th tallest freestanding structure in the world. The Superstack is situated on top of the biggest nickel smelting operation in the world at Vale's Copper Cliff processing centre in the city of Greater Sudbury. In 2018, Vale declared that the stack will be decommissioned and dismantled beginning in 2020. On July 28, 2020, Vale declared that the stack had been officially taken out of service, but would remain operational in standby mode for two more months as a backup in case of a malfunction in the new system, after which the dismantling of this Superstack will begin. In addition to further reducing sulfur dioxide emissions by 85 percent, the decommissioning of the pile is expected to cut the complex's natural gas consumption in half.
