 In 1940 , as part of the War Exchange Conservation Act , Canada banned the import of pulp magazines . Popular launched a Canadian edition of Astonishing Stories in January 1942 , which lasted for three bimonthly issues and reprinted two issues of Astonishing and one issue of Super Science Stories . With the August 1942 issue the name was changed to Super Science Stories , and the <unk> was begun again at volume 1 number 1 ; as a result the magazine is usually listed by <unk> as a separate publication from the Canadian Astonishing , but in many respects it was a direct continuation . The price was 15 cents throughout ; it lasted for 21 regular bimonthly issues in a single volume ; the last issue was dated December 1945 . It was published by Popular Publications ' Toronto branch , and the editor was listed as Alden H. Norton .
