The City of Montreal is recognised as a metropolis of immigration. However, it is structurally lagging behind in the professional integration of newcomers. In this respect, in 2021 Montreal still had a higher unemployment rate gap between newcomers and native-born people than in other Canadian cities. In response to this challenge, in 2019 the City of Montreal launched "Montreal Inclusive at Work", an innovative initiative to promote the professional integration of immigrants in Montreal, encouraging their hiring, integration, retention and progression in employment. Deployed in 3 parts (awaken, engage and equip), the initiative mobilised 60 CEOs of Montreal Inc, relied on the creation of a Montreal Employers' Circle, engaged the general public through a "Closed Door Day" awareness campaign, trained through a podcast seen thousands of times and developed a micro-experimentation pathway with cohorts of companies that led to concrete commitments, among others.
