Thank you for the reply, mswope, and I also confirmed with a Google support representative that in order to use Google Assignments (LTI 1.3) that we would have to have Google Workspace for Education Fundamentals [free] but since it requires the extra time-consuming work to manage all the student Google accounts and we do not have additional personnel to manage those then it does not look like we will be using that tool in our Canvas system. I hope Google may add a feature in the future to allow using personal Google accounts for our end users so we can take advantage of the Google Assignments (LTI 1.3) tool.
