Sarah Thomson

In September 2019, Thomson posted a series of Facebook and Twitter comments alleging a Barbadian private school refused to allow her allegedly transgender child to wear a uniform of their choice.

In February 2018, Thomson published an article in Women's Post alleging that inappropriate sexual comments were made to her by an unnamed television host at a luncheon during her 2010 run for mayor. TVOntario confirmed in a statement that Thomson's allegation was directed at Steve Paikin, host of the network's The Agenda current affairs program, and that it was launching a third-party investigation. Paikin denied the allegations, calling them "100% false" and describing Thomson's comments as defamation. The network stated that, "based on the evidence to date, TVO sees no reason to remove Mr. Paikin from his role as host for The Agenda."

In April 2018, the independent investigation cleared Paikin of the allegations made by Thomson.

On March 20, 2014, Thomson arrived at Toronto City Hall in a horse-drawn cart in order to register as a candidate in the 2014 mayoral election. Because of her low poll numbers, she was not included in all-candidates debates although she claimed that she was polling in fifth place.

Her 2014 campaign was known for numerous bizarre antics, including doing her hair in dreadlocks, having a video interview conducted by her grade-school son, and making a music video parody of 'Timber'. Some suggested that she was trying to appeal to Blacks using these cultural signifiers despite being Caucasian.

On September 3, 2014, Thomson posted a poll on her website asking voters whether she should continue her candidacy for mayor or withdraw and run for city councillor instead. On September 9, two days before the deadline for candidate registration, Thomson withdrew from the mayoral election and registered as a candidate for councillor for Ward 20 Trinity—Spadina instead. She garnered less than 10% of the votes, placed third and lost to Joe Cressy.

Since 2013, Thomson has served as Chair and volunteer CEO of the Toronto Transit Alliance, a non-profit organization which builds educational campaigns and advocates for sustainable urban transportation design. The organization hosted the Green Cities 2017 conference in Toronto.

On March 8, 2013 Sarah Thomson accused Toronto's mayor Rob Ford of groping her while he was inebriated - claiming she thought he was on cocaine. This included inappropriately grabbing her buttocks and suggesting that she "should have been in Florida with him because his wife wasn't there." Ford denied Thomson's allegations. Later, two Richmond Hill councillors, who were at the event, came forward stating that they had witnessed Thomson asking her assistant to stage a photograph so it would look like Ford was groping her, so that she could use it against him in the mayoral campaign.

The Women's Post printed a bi-weekly newspaper that transformed into a monthly magazine. In 2012 it again transformed into an online daily publication, womenspost.ca.

On March 9, 2011, Thomson announced that she was planning to run as a candidate for the Ontario Liberal Party in the riding of Trinity—Spadina in the October 2011 provincial election. Thomson was nominated as the party's candidate at a meeting on March 27 and, in the general election, placed second with 18,731 votes, 1,139 votes behind the winner, Rosario Marchese of the Ontario New Democratic Party.

Thomson registered as a candidate for election as Mayor of Toronto on January 4, 2010.

An April 2010 poll by the Toronto Star stated that Thomson had the support of 7% of respondents, but by June a poll showed her support had risen to 17%, putting her in third place.

After running a community newspaper in Hamilton, the Hamilton Examiner, she sold it and established the Women's Post in 2002.

Sarah Thomson, also known as Sarah Whatmough-Thomson, (born 1968) is publisher and CEO of the Women's Post and the volunteer CEO of the non-profit Transit Alliance.
