Sidebar does not appear on pages

Hello - I have installed the Sydney theme on website. I would like to have the sidebar appear on every page with a different widget in each sidebar. I have set the page to default template and have selected the widget that I wish to have appear in the sidebar but the sidebar still does not appear when I view the page. Thank you in advance.
