From Wikipedia:
The Inco Superstack in Sudbury, Ontario, with a height of 380 meters (1,250 ft), is the tallest chimney in Canada and the Western hemisphere, and the second tallest freestanding chimney in the world after the GRES-2 Power Station in Kazakhstan. It is also the second tallest freestanding structure of any type in Canada, ranking behind the CN Tower but ahead of First Canadian Place, and the 27th tallest freestanding structure in the world. The Superstack sits atop the largest nickel smelting operation in the world at Inco's Copper Cliff processing facility in the city of Greater Sudbury.
It was constructed in 1972 by Inco Limited (now Vale) at an estimated cost of 25 million dollars; from the date of its completion until the GRES-2 chimney was constructed in 1987, it was the world's tallest smokestack. Between the years 1972-75 it was the tallest freestanding structure in Canada.

Yes, I was visiting family who live in Sudbury and I thought it was cool. Mind you, I'm in B.C. now and I take the mountains for granted (:->
