Nomination and Campbell ministry Yamamoto expressed interest in pursuing a career in provincial politics in June 2008, when there was speculation that long-time
North Vancouver-Seymour MLA
Daniel Jarvis was going to retire. While Jarvis kept his options open,
North Vancouver-Lonsdale MLA
Katherine Whittred did retire. In the subsequent
BC Liberal Party nomination meeting for the riding, Yamamoto was challenged by former Member of Parliament
Don Bell and former Vancouver city councillor Jennifer Clarke. Yamamoto was considered the underdog but defeated Bell in the second round of the preferential ballot. In the
May 2009 general election, Yamamoto faced former
District of North Vancouver mayor Janice Harris for the
BC New Democratic Party (NDP), acupuncturist Michelle Corcos for the
Green Party, former leader of the
BC Reform Party Ron Gamble, and
BC Conservative Party candidate Ian McLeod. While the riding was previously considered safe for the BC Liberals, Harris was also considered a star candidate for the NDP. Both candidates had awkward moments, with Yamamoto refusing to participate in an all-candidates forum sponsored by the local teacher's association. The North Shore Credit Union, of which Harris was a member and Yamamoto a board member, had donated $7,500 to the BC Liberal Party. Nonetheless, Yamamoto won the election, making her the first person with Japanese ancestry to be elected MLA in BC. In this position she worked with American and Canadian federal officials in resolving
Canada–United States border issues prior to the
2010 Winter Olympics in Vancouver, as well as hosting officials from other governments during the games. She helped coordinate the provincial government response to the US state of
Montana and the
United Nations concerning resource extraction in
Flathead River Valley that was impacting the
Waterton-Glacier International Peace Park; the province implemented a short term ban on mining and oil/gas extraction, followed a permanent ban in a designated area with the
Flathead Watershed Area Conservation Act in 2011. She was a strong advocate of the
Harmonized Sales Tax (HST), as she had been lobbying in favour of its introduction in BC for years prior to running for political office. However, it proved to be an unpopular initiative with 6,786 people in her North Vancouver-Lonsdale riding signing the FightHST group's petition asking for it to be repealed; the FightHST group also considered conducting a recall campaign against Yamamoto. Just prior to his resignation, Premier Campbell shuffled his cabinet in October 2010, moving Yamamoto to the new role of Minister of State for Building Code Renewal.
Clark ministry In the
2011 BC Liberal leadership election triggered by Campbell's resignation, Yamamoto endorsed
George Abbott. She had found all the leadership contenders held similar views on economic issues, health care and education, but that Abbott was the more personable contender. After
Christy Clark won the party leadership and became premier, she promoted Yamamoto to Minister of Advanced Education in March 2011. She toured various post-secondary institutions across the province and announced $1.5 million for healthcare training programs, $500,000 for a First Nations teaching program, and $300,000 to train First Nations aquaculture workers. She rebuffed calls for greater student affordability and provincial funding for the universities, defending the existing student loan program and the existing provincial funding formula, citing the "challenging fiscal environment". She advocated for a greater role for international students, which Premier Clark's BC Jobs Plan called for increasing by 50% within four years the number of international students in BC. The BC Jobs Plan also called for the creation of a new international education council, which seemed to duplicate the existing BC Council for International Education and led to criticism that the government was either re-announcing old measures or unaware of the existing council. Yamamoto supported the creation of the new council, as an independent steering committee with a broader scope. As Minister of Advanced Education, Yamamoto introduced the
Advanced Education Statutes Amendment Act, 2011 (Bill 18), which sought to implement several measures, including harmonizing the federal and provincial student load procedure, expanding the Personal Education Number system which tracks students in the BC educational system to also include private educational institutions, specifying that board members of colleges and universities are to act in the best interests of the institution, and updating the
Architectural Institute of BC's dispute resolution process. The bill was introduced on November 3, 2011, but was not adopted before the winter break. In May 2012, with her father in attendance, Yamamoto introduced the province of British Columbia's formal apology for its role in the
internment of Japanese Canadians during
World War II. Yamamoto was re-assigned as Minister of State for Small Business in September 2012; with her position re-titled to Minister of State for Tourism and Small Business. In July 2015 she was named to the newly established position of Minister of State for Emergency Preparedness. She ran for re-election in
2017, but was defeated by NDP candidate
Bowinn Ma. After finishing her term as MLA, Yamamoto became president of the BC Earthquake Alliance. ==Electoral history==
