GS was injured in a motor vehicle accident on January 1, 2014. She is in a dispute with Aviva over her entitlement to SABS. GS seeks two categories of benefits: attendant care benefits and medical and rehabilitation benefits. Aviva has denied the attendant care benefits on the basis that GS did not apply for them in a timely manner. It has denied the medical and rehabilitation benefits because, in its view, they are not reasonable and necessary given the nature and scope of GS’s injuries.
