He is the 35 th person to receive that honour.
Milstein was presented with his plaque and a one-year bus pass at the Chamber of Commerce luncheon on Wednesday afternoon at the Rimrock Café.
As of this year the award no longer includes a reserved underground parking spot in the village.
Milstein, who was a driving force in the establishment of Millennium Place and who more recently spearheaded three community greenhouse projects, said he was honoured to receive the award.
Jill Ackhurst was also named honorary Citizen of the Year at the luncheon.
Ackhurst passed away at Christmas and her son Michael accepted the award on her behalf.
During her time in Whistler Ackhurst was the chair of the Whistler Community Services Society, an active member of the Whistler Rotary Club, an adult educator with First Nations, among many other things.
This year there were 13 nominations for Citizen of the Year, which is more than ever before.
Eighteen of the past Citizens were on hand at Wednesday’s luncheon for the presentation.
