These releases were never produced in Canada, but were imported mostly from the UK, and some from the USA. They are listed here because they were readily available in stores in Canada, but worldwide distribution started to originate from the same few pressing plants.
In recent years though (2017 to present), a number of "foreign" pressings have a "Made in Canada" sticker or print on the shrink wrap. It seems that Universal Music subcontracted local manufacturers when needed, and sent plates and/or artwork to Canada and other countries, but they are not "Canadian pressings" as they were only manufactured in Canada, and not necessarily marketed and distributed in Canada. These new "Canadian pressings" seem, more often than not, to be below the standards of the original local pressings from the 60s; these subcontracted runs are often made with newer small operations that do not necessarily have the experience of the old corporate plants from the 60s and 70s.
