Yes, you can download the manual for the firearms safety course we give in Toronto here (http://publications.gc.ca/site/eng/9.801815/publication.html) so that you can start studying immediately. Even better, a recent change in policy about electronic devices in the classroom now allows for students to use the downloadable version in the classroom, provided there is no recording of the course by use of the electronic device.
So, if you have a chance to review some of the material before the Canadian Firearms Safety Course, it can help lay the groundwork for success later during the course. To begin your journey, book your course here: https://firearmstoronto.ca/courses/
