About Sudbury

The story of Sudbury

Sudbury, officially known as Greater Sudbury, stands as the most populous city in Northern Ontario and one of Canada's largest municipalities by land area. It rests upon the rugged Canadian Shield, its very identity shaped by a unique geological history—it lies within the Sudbury Basin, an ancient meteorite crater formed 1.85 billion years ago. This monumental impact created abundant deposits of nickel and copper, carving Sudbury's identity as a global mining center.

Beyond its industrial origins, Sudbury has undergone a remarkable transformation. Once marked by a stark landscape due to historic smelting activities, the city embarked on an ambitious regreening program in 1978, planting over 10 million trees and rejuvenating its environment. Today, Sudbury is celebrated as the "City of Lakes," containing 330 freshwater lakes within its municipal boundaries—more than any other city in Canada. It functions as a significant retail, economic, health, and educational center for Northeastern Ontario, with a thriving Franco-Ontarian population enriching its arts and culture.

Visitors to Sudbury can explore its compelling geological past and ongoing scientific endeavors, immerse themselves in its natural splendor, and experience a city that has successfully diversified beyond its resource-based economy. With its blend of urban conveniences and extensive outdoor offerings, Sudbury provides a distinctive Northern Ontario experience.

History

## From Railway Camp to Mining Capital Sudbury's origins trace back to 1883 as a temporary labor camp during the construction of the Canadian Pacific Railway. The settlement was named by railway superintendent James Worthington, honoring his wife's hometown in Suffolk, England. The discovery of vast deposits of nickel and copper ore in 1883 during railway blasting swiftly transformed this outpost into an industrial center.

By 1886, companies like Canadian Copper were formed to exploit the region's mineral wealth, with smelting operations commencing in 1888. Sudbury was incorporated as a town in 1893, and by 1902, the International Nickel Company (INCO) was established, becoming a dominant force in the regional economy. By 1915, Sudbury's mines supplied 80 percent of the world's nickel, a supremacy further solidified by the founding of Falconbridge Nickel Mines in 1928.

For much of the 20th century, mining and related industries dominated Sudbury's economy, employing a significant portion of the population. However, this rapid industrialization came at an environmental cost, leading to a largely barren landscape due to heavy smelting and acid rain.

## Environmental Reclamation and Diversification In response to environmental concerns, Sudbury launched an ambitious regreening program in 1978, which has seen over 10 million trees planted, significantly revitalizing the landscape. The construction of the Inco Superstack in 1972, at 381 meters (1,250 feet) the tallest chimney in Canada and the Western Hemisphere, was part of an effort to disperse emissions away from the immediate area.

Sudbury was granted city status in 1930 due to its rapid growth. In 2001, the City of Greater Sudbury was formed through the amalgamation of several towns and unincorporated townships, creating a single-tier municipality. Today, while mining remains important, Sudbury has diversified into a regional capital for financial services, healthcare, education, and tourism, with three post-secondary institutions: Laurentian University, Cambrian College, and Collège Boréal.

What to see

Begin your exploration at Dynamic Earth, an immersive earth sciences center where you can delve into Sudbury's mining history and unique geology. Do not miss the chance to descend seven stories underground on a guided mine tour, experiencing the evolution of mining firsthand. Outside, pose for a selfie with the iconic Big Nickel, a 9-meter (30-foot) replica of a 1951 Canadian five-cent coin, symbolizing Sudbury's contribution to the Canadian economy.

For a broader scientific journey, visit Science North, Canada's second-largest science center. Housed in two snowflake-shaped buildings, it features interactive exhibits, a digital planetarium, an IMAX with Laser theatre, and a butterfly gallery.

Embrace Sudbury's natural splendor at Bell Park, a waterfront expanse on Ramsey Lake with boardwalks, gardens, and beaches. You can also explore the extensive trail networks at Lake Laurentian Conservation Area or Kivi Park, offering opportunities for hiking, mountain biking, and paddling. For art enthusiasts, take a self-guided tour of the city's lively outdoor murals in downtown Sudbury, including a tribute to Alex Trebek.

When to visit

The best time to visit Sudbury for warm-weather activities is from late June to late August. During these summer months, average high temperatures reach around 25°C (77°F), making it ideal for exploring the city's numerous lakes, trails, and outdoor festivals. Fall, from September to November, also offers a pleasant experience with beautiful autumn foliage. Winter, from December to February, brings cold, dry weather and snowfall, perfect for activities like ice skating on Ramsey Lake or snowmobiling on groomed trails.

Practical

Sudbury is easily accessible by car, located at the convergence of Highways 69 South and 17 (part of the Trans-Canada Highway). VIA Rail and Ontario Northland bus services also connect Sudbury to other urban centers, and the city is serviced by the Greater Sudbury Airport. While the city's extensive land area means residents often rely on driving, many attractions are concentrated or accessible via public transport or walking/cycling paths. The city offers a range of accommodations, from hotels to campgrounds. For local events and activities, check the Discover Sudbury website. If you plan to host an event on city property, permission is required, and details can be found through the City of Greater Sudbury's Parks and Recreation Services. Remember that the climate is seasonal, so pack accordingly for warm summers and cold, snowy winters.
