01

Evidence hierarchy

Regulations and official guidance govern policy claims. Technical standards and peer-reviewed research inform process and lifecycle explanations. Commercial claims are not treated as neutral evidence.

02

Update practice

Policy pages are reviewed when federal or provincial frameworks change. Lifecycle pages retain the date and method of any future quantitative comparison.
