His imprint on Chinatown is undeniable. Along with being the architect of the Dr. Sun Yat-Sen Classical Chinese Garden, the Chinatown Millennium Gate, the Chinese Cultural Centre Museum and Archives, the Chinatown Parkade and Plaza, and the Commemoration of Block 17, Wai has been involved in the many restorations of the neighbourhood’s historical Society buildings. Known for his activism, Wai got his start volunteering with the Strathcona Property Owners and Tenants Association (SPOTA), saving numerous families from the perils of land expropriation and demolition, while weaving fifty some homes into the neighbourhood.
