Early in the film, Beth drops Josh off at Vincent Massey School, which happens to be a real school in Calgary, Alberta. Later, however, at about 12m, Josh's Red Cards (discipline notices) say "Coleman's Elementary School."
Dr. Seager shows Elizabeth a video on his computer. However, not only is it running a very old version of Windows (3.1 or 95), the desktop is empty apart from a single folder (My Documents) containing one video. Hardly the computer of a successful therapist.
You can clearly see the mic on the back of Jenna (Sara Canning) under her t-shirt at 1:13:38 before she was running from the train.
