Once you are registered in a course, take a look at the syllabus
and proceed to find the required textbooks for the course. Once
you know what you need, contact the university bookstore using email.
It is a simple process where you can email (fax and phonecalls are also permitted) your list of required textbooks and your credit card information. From there, the textbooks are sent to you within two weeks if you reside in Canada.

Some other methods of buying your textbooks include looking at
commercial online bookstores such as Chapters-Indigo, Chapters, and Amazon or going buying second hand books.. These
bookstores might carry what you need; however, take into consideration the exchange rate and the delivery costs.
