COVID-19 pandemic made life very difficult for the city’s most vulnerable, according to the 2021 version of its Vital Signs report.The latest study from the Hamilton Community Foundation (HCF) paints a picture of how life in the city was aggravated by the pandemic and for the most part, negatively affected people living in multigenerational households, those precariously housed, and those working in front line services.Terry Cooke, president and CEO of Vital Signs Hamilton, says the research shows those groups typically have lower incomes and “blue collar” jobs which generally made them more susceptible to contracting COVID-19.
