Skilled workers and their dependents are the largest group of economic immigrants in Canada. Their labour market integration is critical for immigrant well-being as well as host country economic productivity. However, immigrant professionals face significant barriers to workplace integration, including unfamiliarity with workplace norms and practices. Participants of this study described challenges related to workplace communication and interactions, adaptation to new workplace cultures, recognition of qualifications and experience, and professional outcomes. They identified general professional values, skills, and capacities, and communication and relationships perceived as essential for workplace integration. Strategies for supporting workplace integration included continuing learning and education, training on cultural diversity and workplace skills, professional field experience, and professional mentorship. These findings have implications for practice and policies facilitating the workplace integration of immigrant professionals in Canada, including training and mentorship approaches.
