Webcanvas is open source so you can actually check. If you check out the quiz log history you’ll see the two major ‘cheating’ countermeasures are inactivity and and window/tab. Webthe canvas platform does not have internal proctoring tools to actively track tabs or see if students switch screens on their computers. However, many educational institutions. Webcan teachers see when you open or switch tabs during canvas quiz? Webi know at least during a quiz/test/assignment, canvas monitors all your activity on that tab. Which question you look at, which answer you selected, etc. Also if you change tabs or windows. Everything is time stamped. So to answer your question, yes. 😬 edit:
