[9] She had a dispute with Burnaby MLA Patty Sahota over what Corrigan believed was political interference[10][11] and with a fellow board member who attributed good performance at school to specific ethnicities.

[14] The Burnaby-Deer Lake riding was created in a boundary re-alignment with BC Liberal John Nuraney as its incumbent MLA.

The NDP hosted a public event to oppose locating the remand centre at the selected site[18] and Burnaby City Council issued a resolution stating their opposition.

[19] While the incumbent MLA Nuraney defended it,[20] BC Solicitor-General John van Dongen announced the site selection would be re-considered with the advice of Metro Vancouver.

[25] When the government claimed the Olympics had cost $925 million, which was $325 million over budget, Corrigan estimated that the actual cost was closer to $1.2 billion if indirect expenses, such as upgrades BC Place Stadium and the SkyTrain system, and the expenses associated with the 650 public service employees that were reassigned to the games, were factored in, and that VANOC should not have reported a balanced its budget with government transfers and crown sponsorships claimed as revenue.

[26][27][28][29] She also asked for provincial and federal government advocacy directed at VANOC and the IOC over their decision not to include females in the ski jumping event.

[30] Along with neighbouring NDP MLA Raj Chouhan, she co-wrote letters to editors and participated in public events opposing the Harmonized Sales Tax.

While both Kathy and Derek Corrigan were cited as being viable candidates[38] in the subsequent BC NDP leadership election, both declined and, in January 2011, endorsed John Horgan.

[39] After Adrian Dix won the leadership election, he kept Corrigan in her role as critic on women's issues and on Public Safety and Solicitor General.

[41] She advocated that the province should cover the full costs of the 2011 Stanley Cup riot review, rather than cost-sharing with the Metro Vancouver municipalities[42] and sought to have the Legislative Assembly join Ontario and Quebec in lobbying the federal government for funds to implement the proposed Safe Streets and Communities Act.

[48] Following the election Dix adjusted the critic roles so that Corrigan would focus on issues related to public safety and the Solicitor General.
