10th ed. McGill Guide continues to recommend an EN dash (not a hyphen) for ranges. This makes sense and is consistent with other style guides. However, they've changed all of their examples to use an EM dash. In the 9th edition, this error was only in a single example. Now it has spread everywhere.

I like that the Court of Appeal Rules (BC) are organized by headings that read like an FAQ: www.bclaws.gov.bc.ca/civix/docume...
