Canadian reference
Sourced answers, with the date they were checked.
Each page states one figure or rule, links the official Canadian source, and shows the version and next review date. If a figure passes its review date it stops being presented as current rather than quietly continuing to answer.
Where these come from
Every entry is drawn from the public rule registry that the calculators themselves use. Nothing is written by hand here, so a corrected figure changes the tool and the reference page together.
