Elite Canadian Growth Stocks To Own In October 2026

AI infrastructure spending is pulling huge amounts of cash into data centers and digital services, even as some tech giants report pressure on devices and consumer budgets. Growth-focused Canadian companies where executives own meaningful stakes can look interesting when every dollar of investment matters. This article highlights three such fast growing businesses with high insider ownership, drawn from one screener, to help you find ideas aligned with management.

The three stocks highlighted here offer a compelling starting point if you want exposure to fast growing businesses where insiders have meaningful skin in the game. However, if you want the absolute best, these 10 high growth high conviction stocks are the cream of the crop.

Tenaz Energy (TSX:TNZ)

Overview: Tenaz Energy is a Calgary based producer focused on North Sea natural gas in the Netherlands, with complementary Canadian oil and gas assets.

Operations: Tenaz Energy records CA$497 million from petroleum and natural gas sales, with roughly CA$460 million generated in the Netherlands and CA$38 million in Canada.

Market Cap: CA$2.51b

Tenaz Energy matters for this high growth, high insider ownership theme because its Netherlands gas project puts management led expansion plans right at the forefront of the story.

"The build out of high quality Netherlands gas production, supported by multiple rigs across TEN operated, ONE Dyas operated and ENI operated wells, increases exposure to European gas pricing and can support higher revenue as more volumes move into the sales mix."

What happens to those projected margins and cash flows depends heavily on how one unseen pressure on future European gas economics plays out.

That hidden pressure on future gas economics is exactly what the full narrative for Tenaz Energy unpacks, including where Tenaz Energy could accelerate or stall if conditions shift.

Aritzia (TSX:ATZ)

Overview: Aritzia is a Vancouver based fashion retailer that designs and sells its own women's apparel brands through boutiques and fast growing digital channels in Canada and the United States.

Operations: Aritzia records CA$4.35b of apparel revenue, with about CA$1.55b generated in Canada and roughly CA$2.79b in the United States.

Market Cap: CA$17.35b

Aritzia matters for a fast growing, high insider ownership theme because its own brands and direct channels give management clear levers to scale, especially as more shoppers shift toward its online storefront and new U.S. boutiques.

"Aritzia's ongoing U.S. boutique rollout, with new locations reportedly paying back in under one year and management indicating room to expand from roughly 76 to 82 to at least 180 to 200 boutiques, points to a continued store-led uplift to net revenue."

What happens to that earnings path depends heavily on how one quiet margin pressure tied to those growth plans ultimately plays out.

That quiet pressure is exactly what the full narrative for Aritzia unpacks, revealing how Aritzia's growth ambitions, capital intensity and insider alignment could either accelerate or stall the story.

Ivanhoe Mines (TSX:IVN)

Overview: Ivanhoe Mines is a Vancouver based miner focused on copper growth from the Kamoa Kakula Copper Complex, alongside zinc and PGM projects in Africa.

Operations: Ivanhoe Mines reports about $575 million of revenue from Kipushi Properties, with smaller segment adjustments shaping the final reported figure.

Market Cap: CA$13.9b

Ivanhoe Mines appears in this fast growing, high insider ownership screen because the Kamoa Kakula Copper Complex concentrates much of management and analyst attention on one large, expanding copper asset that could reshape the business over time.

"Catalysts stacked (Phase 3/4 Kamoa ramp to >550 ktpa medium-term, Platreef Phase 2, Kipushi de-bottlenecking, smelter online, Project 95 recoveries, exploration)."

The outcome of that growth narrative depends on how future copper pricing and cost pressures ultimately balance out.

That balance of copper prices and costs is exactly what the full narrative for Ivanhoe Mines breaks down, showing where Ivanhoe Mines could see accelerating upside or risk quietly building.
