The Progressive Democratic Alliance (PDA) was a centrist political party in British Columbia, Canada founded by Gordon Wilson, Member of the Legislative Assembly (MLA) for Powell River—Sunshine Coast.
After losing the leadership challenge to Gordon Campbell, who in turn led the party to victory in the 2001 provincial election, Wilson and Tyabji left the party to establish the Progressive Democratic Alliance on December 5, 1993.
In the subsequent June 26, 1996 general election, Wilson retained his seat, while all 65 other PDA candidates, including Tyabji, were defeated.
The PDA was disbanded by Wilson in 1999 when he joined the ruling New Democratic Party of British Columbia to become a member of Cabinet.
Finding financial obstacles, they instead formed the British Columbia Democratic Alliance, billing it as a successor organization.
