Standing at a height of 1,250 feet, the Sudbury Superstack is the second tallest chimney in the world and runner-up to the CN Tower for the tallest structure in Canada. Until 1987, Sudbury Ontario had the dubious honour of having the world’s tallest smokestack. Today, the Stack is seen by some as a marker for Sudbury’s rich mining heritage but for others, it is also part of a much larger history of health and environmental problems.
Since the nineteenth century, Sudbury’s landscape was ravaged by the effects of the mining industry; over the years the vegetation disappeared with acid rain, and farmers found themselves unable to grow crops in the highly acidic soil. The International Nickel Company (INCO) built the Superstack in 1972 to disperse sulphur dioxide (SO2) and other pollutants away from the area, thereby addressing health and environmental concerns. The Stack’s construction coincided with a community regreening movement, which has reversed some of the environmental damage. The Superstack reduced local emission rates in recent years, but one could argue that INCO simply passed the buck, and the dispersion of SO2 became somebody else’s problem. Moreover, the Sudbury area continues to have higher rates of asthma and lung cancer than other parts of Ontario. For better or for worse, the Superstack has been a landmark along the Sudbury skyline for over forty years. And when Vale (formerly INCO) recently proposed demolishing the Superstack in the local media, we watched as an interesting public debate about the significance, history, and future of the stack ensued.
On November 3rd 2014, Kelly Strong of Vale announced that the company considered demolishing the Superstack. This news is not surprising and is in keeping with Vale’s ongoing $1 billion Clean AER Project, designed to reduce SO2 emissions. If the Superstack is removed it will be replaced by a smaller chimney, but this will mark a big departure not only in the company’s operational history, but for local history as well.
We realized that as historians, we can help curate and analyze the varying memories and opinions people shared about the Stack. A brief snapshot of the conversation on the Northern Life’s Facebook page reveals that many Sudburians have a strong connection with the Superstack. While several people questioned whether the Stack deserved to be classified as an iconic landmark, a great deal more believed it represented a part of Sudbury’s history and it should be preserved.
Sudburians argued that the Superstack was a beacon of homecoming; seeing the Stack jutting out of the skyline filled them with a sense of nostalgia and the realization that they were home. Commentators also noted that the Stack is often used by residents and outsiders to locate Sudbury. Some might say, “oh, you’re from the city with the giant smoke stack,” or, “Sudbury has the Superstack, right?” Not only do locals identify the Superstack with ‘home,’ but residents and visitors also use it to situate themselves in place. The potential absence of the Superstack as a physical reference point along the Sudbury horizon could create a (harmless yet interesting) sense of loss and dislocation for some.
We found that the Stack is also a site of memory used to recall family histories. Residents fondly recounted memories of their parents or grandparents building the Stack, while others boasted of their relatives surviving Sudbury’s August 1970 tornado from high atop the chimney. The Stack is also a marker that roots blue collar workers and their families in place. It is an archive that embodies histories of work and family.
In the Northern Life, Jonathan Migneault refered to the Stack as both an eyesore and an iconic landmark. Is the Stack nothing more than an industrial remnant? Deindustrialization is not just an economic process but a social one as well. The demolition of industrial sites are complex and emotional events for locals, especially for individuals who worked for decades in a single-industry town. Although the Stack is technically still functional, its replacement with a smaller chimney would mark the end of one era and the beginning of another.
Historian Steven High studied the sense of loss and dislocation experienced by residents of Sturgeon Falls, Ontario, who struggled with the closure and demolition of their paper mill in the early 2000s. “What happens to a mill town that loses its mill?”, High questioned. High discovered that a part of local identity and history was lost when the paper mill was demolished. The physical absence of the mill served as a poignant reminder that prosperous times had come and gone in Sturgeon Falls. What will happen to Sudbury if it loses its Superstack? As the Sudbury economy continues to diversify, shifting away from mining towards other industries, its industrial landscapes will be renegotiated, rebuilt, or perhaps erased.
Beyond the social media debates, the image of the Superstack boasts economic value for members of the community who use it to brand their products and services. Sudbury craft brewers Stack have tasted success, largely because of their quality beers, but also due to their savvy marketing campaign. Stack’s brand is aimed at a new generation of local consumers who embrace the Superstack somewhat nostalgically. The Stack brand evokes notions of home, nostalgia, and local identity for Sudburians, with beers labeled “Black Rock” (Sudbury is notorious for its black rocks, a product of nickel smelting), “Valley Girl” (based on the”valley” communities on the outskirts of Sudbury, such as Hanmer and Chelmsford), and “Saturday Night” (a nod at Stompin’ Tom Connors’ song, Sudbury Saturday Night).
The Superstack is an oddity, a symbol of pollution and environmental damage, and an eyesore for a lot of people. But this giant chimney also holds complex and sometimes competing meanings to many generations of Sudburians. What is clear is that the significance of the Superstack transcends its industrial function. It will be interesting to see what Vale decides in the coming months and how this will be received by Sudburians. Since Strong’s announcement, the Sudbury Star polled readers about the potential demolition; fifty-nine percent said they would not miss it, while thirty-eight said they would, and three percent were unsure. Will we see “Save our Stack” petitions circulating, or will the response be more muted? Whatever the case, as historians, we might enter the debate, but we will also strive to observe and listen to the memories, stories, and meanings that are attributed to the infamous Superstack.
