Copies of a book promoting white nationalist ideology have been placed in community-run library boxes in neighbourhoods in parts of Ottawa, prompting a police investigation.

Christine Young found several copies earlier this month when she decided to check out a few little free libraries near her home in Barrhaven.

Young, a federal government consultant, never expected to repeatedly come across the same book — one that denounces immigration, multiculturalism, advocates for a white ethnostate in which racialized communities would be classified as second class citizens.
