Healthcare covers a wide range of work, including transactional, advisory and contentious matters. By its nature it is extremely wide-ranging, often leading lawyers to consolidate expertise in specialist areas such as procurement, commissioning, healthcare technology or financing work. Transactional work is primarily the sale and purchase of some or all of a health system or health insurance company. Law firms advise on competition issues and assorted regulatory matters for clients such as hospitals, health systems and insurance companies. In Canada healthcare litigation includes a strong focus on medical malpractice defence. This section also takes into account healthcare privacy and mental health law, as well as healthcare human resources and labour relations law. Please also see Product Liability for litigation arising from pharmaceutical and medical devices defects. The regulation of these areas also features in our life sciences chapter.
