How WageWise Canada Handles Rate and Rule Changes

See how WageWise separates effective-date data, calculation logic, content review and public change notices.

Key point

A calculator should select a rule by the work date, not simply overwrite an old rate. Material formula, coverage and source changes are versioned, tested and logged.

Store rates with effective-from dates and source links.
Keep old versions when users may calculate historical periods.
Re-run boundary fixtures and publish material changes.

Monitoring and verification

Scheduled reviews focus on government announcements, statutes, regulations and official policy pages. Secondary commentary can flag an issue but does not replace the controlling source.

Effective-date versioning

A new rate is added as a dated rule. The prior rule remains available for earlier work dates. Formula changes receive a version label and calculation fixtures for the old and new boundary.

Release and correction records

Calculator releases, material rule changes and corrections are recorded in the Updates area and central update history. Review dates describe what was checked, not a guarantee that every scenario is covered.
