This dissertation explores the phenomenon of increased use of online discussion forums by newcomers to Canada to access labour market knowledge. Drawing on extant literature on social support, knowledge exchange, and online technology affordances, I examine the role of online discussion forums in newcomers' labour market integration, through an inductive content analysis of 574 discussion threads. Results of this study suggest that the role of online discussion forums is to provide knowledge resources, in the form of information and advice support, which help newcomers make migration decisions and manage their expectations and preparedness, which in turn has the potential to help newcomers with adjustment and labour market integration in the new country.Lastly, I would like to thank and dedicate this dissertation to my parents for their endless patience, encouragement and optimism.iv
