Step-by-step explanation:
The fastest growing type of worker in Canada over the last twenty-five years has been the knowledge workers. This group includes individuals in professions that require significant education and training, often leading to lucrative career choices.
Alongside, the health care workers category has seen expansive growth, part of which may be attributed to an aging baby boomer population requiring more intensive elder care services. The importance of specialization in skilled professions has led to greater efficiency and the development of innovative methods to enhance productivity across various sectors, including manufacturing, personal services, and healthcare.
