1976: the CN TOWER, the tallest structure of Canada, was built in Toronto.
1987: the chimney of the GRES-2 Power Station was built in Ekibastusz, Kazakhstan. It was the tallest chimney ever built.
But before these structures got built, something else was the tallest chimney in the world, and the tallest structure of Canada. Inco Limited (now Vale) built it in Sudbury, Ontario, next to the area called Little Italy.
For 15 years the Inco Superstack was the tallest chimney in the world, and one of the tallest structures. It’s 380 meters tall (1250 ft), almost like the Empire State Building, and it’s still there, eternally second, but with a lot of strength and pride.
