About Maple Value Screener

Why This Exists

Most stock screening tools are either paywalled, US-focused, or both. Canadian investors who want to apply systematic, evidence-based approaches to stock selection have limited free options.

Maple Value Screener was built to fill this gap: a free, transparent, Canadian-focused stock ranking tool that anyone can use, verify, and learn from.

Why Canada?

The TSX (Toronto Stock Exchange) is home to hundreds of publicly traded companies across energy, mining, financials, technology, and more. Yet most public screening tools focus on US markets. Canadian stocks deserve the same quality of analysis tools.

By focusing on TSX-listed common stocks, we can build deep, consistent coverage rather than spreading thin across global markets.

What Makes It Transparent

Unlike many financial sites, we show our work:

  • Every formula is documented on the methodology page
  • Every input value is visible on stock detail pages
  • Data dates are shown so you know how fresh the information is
  • Simplifications are acknowledged rather than hidden
  • Quality flags highlight potential data issues
  • Rankings are exportable as CSV for independent analysis

Why Results May Differ From Other Screeners

No two screeners produce identical results, even when using similar formulas. Differences arise from:

  • Different data sources and update frequencies
  • Different stock universe definitions
  • Variations in how financial fields are extracted and normalized
  • Different handling of edge cases (negative values, missing data)
  • Different exclusion rules for sectors, company types, or minimum sizes

We consider this a feature, not a bug. Multiple independent perspectives on the same data can be more valuable than a single source of truth.

Open and Free

Maple Value Screener is built with:

  • No paid APIs or data subscriptions
  • No paywalled features in the core ranking tool
  • Publicly described formulas that anyone can verify
  • Open-source tools and free-tier infrastructure

The goal is to make quality stock screening accessible to everyone, not to create another subscription service.
