Harder's Conservative platform included a focus on the expansion of the energy sector, and the completion of pipelines. Issues relating to environment were the end of carbon pricing in Canada, as well as the prohibition of dumping sewage in waterways, such as the West Coast and the St. Lawrence River. Harder also cited crime and the opioid crisis as a major issue to be tackled, as well as an advance of aid to local peace officers.
In 2011, Harder told Christian Week that many public school teachers in Alberta encourage sexual experimentation, which Harder believes results in unsafe sexual activities.
Abortion stance
Harder is opposed to abortion, except where necessary to protect the life of the mother. The pro-life organization Campaign Life Coalition gave Harder a near-perfect voting record and she has said that she will "always advocate for the preborn". She has voted to fund resource centres that provide aid for pregnant women but do not offer abortions, and gave two centres in her riding $12,000 in federal grants. Harder also co-sponsored Bill C-225 in January 2016, which would have made it "an offence to cause injury or death to a preborn child while committing or attempting to commit an offence against a pregnant woman and to add pregnancy as an aggravating circumstance for the purpose of sentencing". In September 2017, Harder was nominated by Conservative Party leaderAndrew Scheer to chair the parliamentary committee on the Status of Women. However, MPs from other parties walked out and a vote did not occur due in protest to her pro-life position. Liberal MP Monsef explained that the committee "decided that having their spokesperson, and their chair, be someone who does not support a woman's right to choose, is not supportive a person's rights, is not the best choice".
Criticism of carbon taxation
Harder is opposed to the implementation of the Greenhouse Gas Pollution Pricing Act, stating it will increase household debt and will not be effective in its goal to reduce green house gas emissions. Her critique of Carbon Pricing extends to Canada's involvement in the Paris Accord, stating that the targets are too high for Canada to meet. Harder also is an advocate for higher government transparency with regards to carbon pricing, criticizing the Liberal Party of Canada's fiscal expenditures.
