Understanding Canadian Insider Trading Filings

In Canada, corporate insiders — executives, directors, and major shareholders — are legally required to disclose every time they buy or sell shares in their own company. These disclosures are filed through SEDI (System for Electronic Disclosure by Insiders), Canada’s national insider reporting database. Understanding how these filings work is the first step to using them as an investment signal.


What Are Insider Trading Filings?

Insider trading filings are mandatory regulatory disclosures required by Canadian securities law. Any time an insider of a publicly traded TSX, TSX-V, CSE, or NEO company buys or sells shares, they must report that transaction to SEDI within a defined window — typically within 5 calendar days of the trade date.

The filing includes the insider’s name, their role at the company (CEO, Director, VP, etc.), the number of shares traded, the price paid, and their updated share balance. This data is public and forms the backbone of insider tracking platforms like TSX Insider.

Who Is Considered an Insider?

Under Canadian securities law, insiders include:

  • Directors and officers of the company (CEO, CFO, COO, VP-level and above)
  • Shareholders owning 10% or more of the company’s outstanding shares
  • Individuals with access to material non-public information
  • Certain family members and affiliated entities of the above

Types of Insider Filings

Insider Reports (Primary Filing)

The most common filing. Filed after every open-market purchase or sale. These are the trades tracked by TSX Insider — real money, real conviction, reported publicly within days of execution.

Early Warning Reports

Required when a shareholder acquires 10% or more of a company’s shares. These signal potential control bids or major strategic accumulation and are watched closely by institutional investors.

Material Change Reports

Filed when a significant development occurs that could affect the company’s stock — such as a merger, major contract, or executive departure. These accompany, but are separate from, insider trade filings.

Why Do These Filings Matter to Investors?

Insiders have the deepest knowledge of their company’s operations, financials, and pipeline. When a CEO or director spends their own money buying shares on the open market — especially in size — it often signals genuine confidence in the company’s direction. Unlike analyst estimates or press releases, insider purchases are backed by real capital at risk.

TSX Insider filters and ranks these trades by size, role, and pattern — highlighting Notable trades ($20K+, 10%+ balance increase) and Significant trades ($50K+, 20%+ balance increase) — so you can focus on the buys that actually move the needle.

How to Read a SEDI Filing

Each SEDI filing contains:

  • Insider name and title — role matters. A CEO buy carries more weight than a minor shareholder.
  • Transaction date — the actual trade date, not the filing date.
  • Number of shares and price — total dollar value reveals conviction level.
  • Post-trade balance — the percentage increase in their holdings is a key signal. A 30% increase in share balance is far more meaningful than a 0.5% top-up.
  • Transaction code — TSX Insider tracks code 10 only (open market purchases), filtering out option exercises, gifts, and other non-cash transactions.
