All lectures will be held in classroom 3-10 located on the west side of the third floor of Cameron Library. It is a leisurely walk of about 10-15 minutes from the Lister Centre.
You will find both the Lister Centre and Cameron Library on the UAlberta map here.
Cameron Library (CL) is located just east of the Central Academic Building (CAB), which is itself located on the east side of the Main Quad, the green area in the middle of the campus. Follow the above link and enter "Cameron Library" into the search field. It will show you its location and it also offers the option to give you walking directions from Lister Hall. (Click on Cameron Library (CL) and select "directions", then enter Lister Centre as the origin. The suggested path may not be the most natural one.)
The Department is located in the Central Academic Building (CAB), on the fourth, fifth and sixth floors. The class will meet in Cameron Library, so there may not be a specific need to go to the Department of Mathematical and Statistical Sciences.
There are major renovations taking place in the lower level of the Central Academic Building and ventilation has been shut down for the entire building, so it can become uncomfortable to spend an extended period of time in that building.
