Top AI Tech Stocks in Canada

In this article, we will discuss the top AI tech stocks in Canada.

The artificial intelligence (AI) sector is already a dominant force in the global economy, and its rapid expansion shows no signs of slowing. As businesses pour capital into AI infrastructure, Canadian companies that enable or support these advancements are becoming increasingly valuable. For investors seeking substantial returns, two standout Canadian AI stocks could deliver significant long-term gains. Let us now have a look at top AI tech stocks in Canada.

Celestica (TSX:CLS)

Celestica has emerged as one of Canada’s most promising AI-related stocks. The company specializes in design, manufacturing, hardware platforms, and end-to-end supply chain solutions. It has seen surging demand—particularly from AI-fueled data centre investments—helping it post robust financial results and a remarkable stock performance.

Over the past year, Celestica shares have climbed more than 103%, and over a three-year period, the stock has skyrocketed by nearly 790%. Despite some recent volatility tied to macroeconomic conditions, the company’s underlying growth potential remains strong.

Celestica’s Connectivity & Cloud Solutions (CCS) segment, particularly its Hardware Platform Solutions (HPS) business, is driving this momentum. High demand from Hyperscaler clients for its networking products, especially its 400G and upcoming 800G switches, is propelling revenue growth and margin expansion. As AI training becomes more cost-effective, demand for high-bandwidth, low-latency networking hardware is expected to accelerate, directly benefiting Celestica’s bottom line.

Additionally, the company has recently secured two major customer wins that will allow it to further showcase its AI infrastructure capabilities and cement its position as a leader in the space. With a solid foundation and increasing AI-related demand, Celestica is well-positioned for continued growth.

CGI (TSX:GIB.A)

CGI is a global leader in IT and business consulting and has been aggressively expanding its AI footprint. The company is embedding artificial intelligence and generative AI into its proprietary solutions, refining consulting frameworks, and optimizing its managed services offerings.

Through close collaboration with clients across multiple sectors—including healthcare, finance, and the public sector—CGI is building industry-specific AI solutions, creating AI innovation hubs (“AI factories”), and enhancing user experiences. These efforts have resulted in a growing pipeline of AI-related opportunities.

CGI’s strong position as a trusted advisor in digital and AI transformation has translated into over $4.1 billion in bookings, with a solid book-to-bill ratio of nearly 110% on both a quarterly and 12-month basis. Its total contract backlog has reached an impressive $29.76 billion as of year-end 2024, highlighting long-term revenue visibility.

In addition to organic growth, CGI is pursuing strategic acquisitions to broaden its technological capabilities and expand its client base. Its consistent financial performance, strategic investments in AI, and growing demand for its services make CGI a compelling long-term investment in Canada’s AI ecosystem.

Bottom line

Both Celestica and CGI are top AI tech stocks in Canada as they are strategically aligned with the accelerating AI revolution. With strong fundamentals, visionary leadership, and rising demand for AI-driven solutions, these Canadian stocks could offer investors powerful upside in the years ahead.
