What was a significant change to Canada's immigration policy in the late 20th century?

The significant shift in Canada's immigration policy in the late 20th century was characterized by a notable emphasis on skilled worker immigration and family reunification. This change responded to the evolving needs of Canada's economy and society, as the nation sought to attract individuals who could contribute valuable skills and expertise to the labor market.

By prioritizing skilled workers, Canada aimed to fill gaps in various sectors that required specific expertise and to stimulate economic growth. Additionally, family reunification policies facilitated the immigration of individuals who could be joined by their family members, further enriching Canadian society by fostering community ties and support networks. This dual focus helped create a more diverse and dynamic population, aligning immigration practices with broader social and economic goals.

The other choices presented do not reflect the most significant changes of that era; while the introduction of a points-based system certainly played a role in the immigration framework, it was the overall alignment of skilled labor and family reunification that marked a pivotal shift in immigration policy priorities during this time.
