Debra-Ann Patricia Toporowski (Quw’utsun: Qwulti’stunaat; traditional Chinese: 黃德美; simplified Chinese: 黄德美) MLA is a Canadian politician who has served as a member of the Legislative Assembly of British Columbia (MLA) representing the electoral district of Cowichan Valley since 2024. She is a member of the New Democratic Party, she was appointed Parliamentary Secretary for Rural Health of British Columbia in 2024.

First elected as a councillor for the Cowichan Tribes in 2013, Toporowski was re-elected for five terms. She ran as a candidate for the municipal council of North Cowichan in 2018 and served two terms. At the time of her election as an MLA, she was serving as a councillor in both bodies, amid other engagements including serving as acting mayor for North Cowichan and as the director for North Cowichan on the Cowichan Valley Regional District board. Toporowski previously worked as a constituency assistant for MLAs Bill Routley and Doug Routley.

Toporowski was born and raised in the Cowichan Valley. She is of First Nations and Chinese descent, the child of Ethel Jack and Howard Wong. She had three brothers and two sisters. Her maternal grandparents are Rosie Peter and Stephen Jack from Quamichan, and her paternal grandparents are Chung Yoi Wong and Sue Yee Wong from Duncan. Toporowski was barred from membership within the Cowichan Tribes prior to 1985, due to the provisions of the Indian Act; her mother was forced to relinquish her Indian status due to her marriage to a Chinese-Canadian man. As a result of the passage of Bill C-31, Toporowski was able to regain her status. Toporowski's name in Quw’utsun is Qwulti’stunaat.

Toporowski has been a member of the New Democratic Party since 2005, and had worked as a constituency assistant in the offices of NDP MLAs Bill Routley and Doug Routley for 12 years. Part of her duties as a constituency assistant was monitoring local government and community events in order to keep the MLA updated on local issues, and Toporowski served as a representative for them at community functions.

Toporowski served five terms as a councillor of the Cowichan Tribes, having first been elected in 2013. During that time she served on various committees: the Cowichan Nation Alliance, Cowichan Tribes Treaty, Cowichan Watershed Board, Cowichan Watershed Society, the Duncan Chamber of Commerce, Fishing Committee, Health Advisory Committee, Island Corridor Foundation, Justice Committee, Khowutzun Gaming Corporation, and the Quw’utsun Kw’atl’ Kwa (Ocean) Fisheries Board and Housing Committee Upon her election as MLA, she resigned her seat from the Cowichan Tribes council on November 1, 2024. She was succeeded by D'Arcy Joe Jr., who received the next highest number of votes during the previous election.

She was first elected councillor in the municipality of North Cowichan in 2018, and won a second term in 2022. Upon her election to municipal council, Toporowski became the first elected woman to hold both positions on two councils at the same time, and would serve on both councils until she was elected as MLA. During her tenure as councillor, Toporowski opposed a measure by councillor Christopher Justice which would have discouraged residential development until the passage of an official community plan. She had recused herself from a proposed development that was planned across the local hospital, citing her perceived conflict of interest. She was acting mayor at the time of her nomination as a BC NDP candidate, and served as director for North Cowichan on the Cowichan Valley Regional District (CVRD) board. She had been on a leave of absence since September 5, 2024 in order to focus on the provincial election campaign, and resigned from council on November 1, 2024 following her election as MLA. While not obligated to resign from the municipal council, Toporowski expressed her desire to focus her attention on the responsibilities as an MLA full-time.

Toporowski was acclaimed as the BC NDP's candidate for the riding of Cowichan Valley on May 11, 2024, with Premier David Eby announcing such in Duncan, British Columbia. The riding had been adjusted during the 2021 British Columbia electoral redistribution, and had been represented by Green Party leader Sonia Furstenau, who was vacating her seat to run in the riding of Victoria-Beacon Hill. Toporowski faced four other candidates for the seat: Jon Coleman (unaffiliated, former BC United), Eden Haythornthwaite (independent socialist), John Koury (Conservative), and Cammy Lockwood (Green). Sarah Simpson in the Cowichan Valley Citizen described the riding as having been initially a three horse race, but with the Greens falling out following Fursteneau's departure. Hugh Chan writing for Business in Vancouver noted that due to the reconstituted boundaries, the riding had become more friendly to the NDP, with the redistribution of Green-friendly regions of the CVRD to neighbouring Juan de Fuca-Malahat including Shawnigan Lake. Chan believed that Toporowski could benefit from her membership in the Cowichan Tribes increasing turnout, but that it could be complicated by independent Jon Coleman who was also a Tribes member.

Toporowski was subject to election sign vandalism during her campaign, having her face cut out of one sign and having another melted. Describing the incident as "upsetting," she noted that signs for her municipal runs had been similarly damaged. She recalled her husband and grandson being subject to verbal harassment while putting up signs for her campaign.
