Top Canadian Growth Stocks For October 2026

Canada is wrestling with how much economic cost it is willing to accept to diversify trade away from heavy reliance on the United States. That debate shines a light on businesses that are financially sound and expected to grow earnings quickly, even if trade patterns keep shifting. For investors, this raises the appeal of high quality Canadian growth stocks. This article highlights three such opportunities from a curated screener.

The three stocks covered below are only a starting sample from this healthy high growth idea. The full screen surfaced 54 more companies with equally compelling narratives that are not discussed in this article.

If you want to identify and analyze those additional candidates for yourself, head straight to the Healthy high growth potential screener.

Artemis Gold (TSXV:ARTG)

Overview: Artemis Gold is a Vancouver based miner developing and operating the Blackwater Gold project in central British Columbia, targeting growing gold and silver output.

Operations: Artemis Gold currently generates all reported revenue of about CA$1.39b from the exploration and development of mineral properties in Canada.

Market Cap: CA$9.03b

Artemis Gold sits firmly in the healthy high growth potential theme because the Blackwater mine is already scaling production while major expansions are underway.

"Although Phase 1A is described as a capital efficient expansion that is expected to lift plant capacity by about 33% for an estimated $110 million, the tie-in work around late Q3 or early Q4 and the complexity of doing brownfield construction beside an operating plant leave room for slippage or operational disruption that could affect near term throughput and therefore revenue and earnings."

What ultimately happens to Artemis Gold’s earnings power now hinges on how one unseen pressure shapes future costs and free cash flow.

That hidden cost pressure is exactly what the full narrative for Artemis Gold unpacks, showing how Artemis Gold’s expansion plan could accelerate, stall, or be quietly reshaped by it.

Hammond Power Solutions (TSX:HPS.A)

Overview: Hammond Power Solutions designs and manufactures transformers and related power equipment, including hardware used in EV charging and renewable energy projects.

Operations: Hammond Power Solutions generates about CA$1.06b from transformer manufacturing, with roughly CA$806 million from the United States and Mexico, CA$222 million from Canada, and CA$35 million from India.

Market Cap: CA$3.54b

Hammond Power Solutions is exposed to the high growth potential theme of electrification because its transformers and power equipment sit behind EV chargers, solar projects, and grid upgrades that need reliable capacity as electrification gathers pace.

"Robust and accelerating demand from data center projects, highlighted as the fastest growing segment and supported by ongoing digitization trends, is expected to drive sustained order flow and backlog, positively impacting top line growth and supporting consistent earnings."

What happens to Hammond Power Solutions’ earnings power now depends on how one cost pressure shapes future margins as capacity expansions ramp.

That margin question is exactly what the full narrative for Hammond Power Solutions unpacks, showing how Hammond Power Solutions could convert surging demand into durable earnings power while managing capacity risks.

Theralase Technologies (TSXV:TLT)

Overview: Theralase Technologies is a Toronto based clinical stage pharmaceutical business developing energy activated cancer drugs, while also selling pain focused laser therapy devices.

Operations: Theralase Technologies currently generates about CA$0.8 million in revenue from its Device segment, mostly in Canada with limited US sales.

Market Cap: CA$54 million
