Toronto is widely recognized for finance, technology, real estate, healthcare, and professional services, but manufacturing remains an important part of the city’s economic landscape. The modern Toronto manufacturing industry is far more diverse than traditional factories might suggest. It includes pharmaceuticals, electronics, automotive components, packaging, consumer products, food production, aerospace, advanced engineering, and technology-enabled manufacturing.
The city and its surrounding Greater Toronto Area provide manufacturers with access to transportation networks, skilled workers, research institutions, suppliers, customers, and international markets. Toronto’s location within Ontario also gives companies access to one of Canada’s largest industrial ecosystems.
According to the City of Toronto’s 2025 Employment Survey, manufacturing remained the largest source of jobs within Toronto’s Areas of Employment, accounting for 76,450 jobs. Those employment areas contained 412,100 jobs and 22,530 establishments overall, demonstrating the continued importance of employment and industrial districts to Toronto’s economy.
At the same time, the meaning of manufacturing has changed. Modern manufacturers increasingly combine physical production with engineering, automation, software, research and development, supply chain management, quality control, and data-driven operations.
This article explores five companies that help illustrate the breadth of the Toronto manufacturing industry:
- Celestica
- Apotex
- CCL Industries
- Magna International
- Procter & Gamble
These companies operate in different industries and use different manufacturing models. Together, they provide a useful picture of how manufacturing in Toronto and the surrounding region has developed into a highly specialized and globally connected sector.
Understanding the Toronto Manufacturing Industry
Before looking at individual companies, it is useful to understand what makes manufacturing in Toronto different from the traditional image of an industrial city.
Manufacturing today involves much more than assembling products on a production line. A modern manufacturing company may design a product, source components from several countries, manufacture or assemble parts, test finished products, manage inventory, package goods, and distribute them to customers around the world.
Toronto’s manufacturing ecosystem includes companies working in:
- Automotive manufacturing
- Electronics manufacturing
- Pharmaceutical manufacturing
- Medical and healthcare products
- Specialty packaging
- Consumer goods
- Food manufacturing
- Aerospace and defense
- Industrial equipment
- Advanced materials
- Plastics and chemicals
- Product design and engineering
- Supply chain and logistics
The Toronto region is particularly important because it connects manufacturing companies with a large consumer market and an extensive network of suppliers.
The surrounding municipalities—including Mississauga, Brampton, Vaughan, Markham, Richmond Hill, Aurora, and other communities—form part of the wider industrial network that businesses often associate with the GTA.
This is why a search for manufacturing companies in Toronto can produce companies whose major facilities are technically outside the City of Toronto but remain closely connected to the region’s manufacturing economy.
1. Celestica
Celestica is one of the most recognizable technology-focused manufacturers associated with Toronto.
The company is headquartered in Toronto and provides design, engineering, manufacturing, supply chain, and after-market services to customers across several industries.

Celestica also illustrates how Toronto has moved toward advanced and knowledge-intensive manufacturing. Modern electronics manufacturing requires specialized workers, engineers, quality specialists, supply chain professionals, and technical managers. It also requires sophisticated facilities and close coordination between design and production.
For Toronto, this creates an intersection between technology and manufacturing. Rather than treating manufacturing and technology as completely separate industries, companies such as Celestica demonstrate how the two can operate together.
2. Apotex
Apotex represents another major part of the Toronto manufacturing industry: pharmaceuticals.
Apotex is headquartered in Toronto and operates manufacturing facilities across Ontario. The company describes itself as a Canadian-based global pharmaceutical and healthcare company, with operations covering generic medicines, biosimilars, branded products, consumer health products, and active pharmaceutical ingredients.
Its global headquarters is located at 150 Signet Drive in Toronto.
Apotex currently identifies five Canadian sites, including its Toronto headquarters, with capabilities covering pharmaceutical manufacturing, packaging, warehousing, distribution, and active pharmaceutical ingredient production.
Pharmaceutical Manufacturing in Toronto
Pharmaceutical manufacturing is significantly different from conventional industrial manufacturing.
The process requires strict quality systems, controlled environments, testing, documentation, regulatory compliance, specialized equipment, and carefully managed supply chains.
A pharmaceutical manufacturer may need to manage everything from raw materials and active pharmaceutical ingredients to formulation, production, packaging, quality testing, and distribution.
Apotex operates across several parts of this value chain.
Its Canadian manufacturing capabilities include:

These capabilities demonstrate the technical side of specialty packaging. Packaging manufacturers increasingly need to develop materials that are lightweight, durable, functional, recyclable, visually attractive, and compatible with automated production systems. As a result, packaging has become a specialized manufacturing discipline.
Global Manufacturing Network
CCL’s international footprint is another important feature. The company operates hundreds of production facilities across multiple continents. This allows it to serve customers close to their manufacturing and distribution operations.
For Toronto, having a global company such as CCL headquartered locally creates connections between the city’s corporate sector and international manufacturing markets.
The company’s Toronto presence also supports functions such as management, finance, strategy, technology, and corporate operations while production takes place across its global network.
Why Packaging Is Important to Toronto Manufacturing
CCL shows that manufacturing is not limited to large machinery or automotive plants. Manufacturing can involve highly specialized materials and products that consumers rarely notice.
A label on a medicine bottle, a film used in packaging, a decorated container, or an RFID solution can represent the output of a complex manufacturing process. This makes CCL an interesting example of how specialized manufacturing businesses operate in Toronto.
4. Magna International
Magna International represents the automotive side of the broader Toronto-area manufacturing ecosystem. Magna’s corporate headquarters are in Aurora, Ontario, north of Toronto, making it a Greater Toronto Area manufacturing company rather than a company headquartered within the City of Toronto itself.
