40 years of helping clients recognize their people | CSI STARS

Our Story

As demand for PPE masks and protective items exceeded domestic supply in early 2020, CSI executives reached out to accredited overseas suppliers to help customers. Essentials by CSI was born. Leveraging our established customer support team, infrastructure and supply chains we are able to provide quality personal protective items to the Canadian market, for a reasonable price.

Our promise to you...we will never participate in price gouging. Integrity is our backbone. We believe in doing the right thing, standing behind our promises and treating others with respect. We believe in being open, honest, and transparent with our customers, partners and employees.
