Yep, new building code legislation is banning doorknobs in Vancouver. From Slate:
As University of British Columbia professor Tim Stainton explained in the article, the doorknob ban is in the spirit of a concept known as universal design, which holds that environments should be built to be usable by a majority of people regardless of age or capacity, rather than adapted to meet the needs of the elderly or disabled.
