Before entering politics, Breckner worked as a lawyer. In the
2024 Saskatchewan provincial election, she was the
Saskatchewan New Democratic Party's candidate in the riding of
Saskatoon Riversdale. The riding had been a traditionally NDP stronghold, and had previously been represented by Saskatchewan Premiers
Roy Romanow and
Lorne Calvert. However in the
2020 provincial election the riding had been won by
Marv Friesen of the
Saskatchewan Party. Friesen did not stand for re-election in 2024 citing health problems. Breckner faced Saskatchewan Party candidate and economist Olugbenga Fakoyejo as well as
Green Party of Saskatchewan leader Naomi Hunter. On election day, Breckner received 60.43% of the vote and was elected. Since 2024, Breckner has served as the opposition Shadow Minister for Trade and Export Development. In this role, she has been active regarding Saskatchewan's response to the
2025 United States trade war with Canada. During the trade war, she advocated for a stronger response to American
tariffs, criticizing the Saskatchewan Party government's response as slow and weak. She supported a renewed ban on the purchase of American-produced alcohol by the
Saskatchewan Liquor and Gaming Authority. Such a ban had previously been implemented by the Saskatchewan Party government in March 2025, but had been rescinded just three months later. Breckner has also advocated for increased
infrastructure investment in order to protect the Canadian economy from American tariffs. She has also been an opponent of
Western Canadian separatism. ==Electoral record==
