In order to effectively promote and sustain the health and well-being of newcomers in Toronto, planners, policy makers and service providers need timely and relevant information on the health status, health needs and determinants of health for this population. [...] Mental health and addictions: • Local researchers and newcomers in the community identify high levels of stress and mental and emotional health as priority health issues for newcomers in Toronto. [...] The health of some groups of newcomers declines more quickly than others and is directly affected by social and economic factors that increase health risks and create barriers to preventive care and treatment. [...] Continuing research on the health and well-being of immigrants in Canada is vital to our understanding of this population and to responding adequately to their diverse health needs. [...] However, more work remains to be done in order to meet the health needs of newcomers in Toronto and to provide the necessary conditions and supports that will enable newcomers to stay healthy and to fulfil their potential.
