Historical legal research is now even easier thanks to an updated legislation comparison tool from CanLII.

Users can now select two versions of an act from Federal and Provincial legislation to see what text has been changed between them. Simply click on “Versions”, choose two versions, and hit “Compare”.

Scroll through the text side by side to quickly note any differences. Text will be highlighted in red and green to show what has been removed and added.

The font and formatting of each act has also been standardized to make it easier to compare. CanLII also automatically hides any large sections of unchanged text, so scrolling and loading times are now quicker.

Try it out yourself, or learn more about this handy tool on the CanLII Blog.
