The third floor of Vanier Library smells of gas in the back (by book rows SD 1- SK 152).
Thank you for your comment.
Roofing work is currently taking place (as of Monday, April 18, 2016) on the south-west corner of the VE building. Usually, work is done for the day by 3 or 3:30 PM. Slight tar-like odours might be noticed inside the building, but no special precaution need take place as the product is safe. The project should be done in three weeks or less, depending on weather.
