Trudeau Grope Gate	In 2018, an allegation resurfaced that Justin Trudeau, before becoming Prime Minister, had inappropriately touched a female reporter at a music festival in 2000.

Jane Philpott resigned as President of the Treasury Board in protest. The Ethics Commissioner ruled in August 2019 that the Prime Minister's team had breached ethics rules and that Trudeau and his officials had tried in 2018 to undermine a decision by federal prosecutors.	Liberal Party	2019
2016 SNC Lavalin election donation	On 30 April 2019, it surfaced that SNC-Lavalin made illegal donations to the federal Liberal Party for a period of 5 years ending in 2009. The Liberals received the information in 2016 and did not make it public for 3 years.

For this 1 executive was charged and a compliance agreement was signed with the company to not break the rules again in the future.	Liberal Party	2019
Blackface Scandal	On 18 September 2019, during the federal election, images were published in Time magazine of Prime Minister Justin Trudeau wearing brownface makeup from his time as a teacher at West Point Grey Academy. A total of three images and one video surfaced of three different events when Trudeau wore racist makeup. Trudeau has faced questions since about how his past actions reflect on his ability to lead the country on the issue of racism.	Justin Trudeau	2019
Sole Source Contracts	During an ethics committee meeting on February 10, 2023, International Trade and Small Business Minister Mary Ng faced scrutiny over her decision to award contracts to Amanda Alvaro, a communications professional and Power & Politics panelist, for media training and public relations work. This decision, involving contracts worth $16,950, was criticized by opposition MPs as a breach of federal conflict of interest laws, damaging trust in the government. Ng, who was reprimanded by the ethics commissioner for not recusing herself from the contracting process, justified her actions by stating the need for additional communications support at the start of the COVID-19 pandemic in 2020 to manage an increased volume of media requests while distributing federal support to small businesses.	Mary Ng	2020
WE Charity controversy	Prime Minister Justin Trudeau announced on 25 June 2020 that the government had chosen WE Charity to run the long-promised $912 million Canada Student Service Grant. Following complaints by opposition parties that the Trudeau family had ties to WE Charity, the Ethics Commissioner on 3 July 2020 announced an investigation into Trudeau's and the government's decision to have the charity administer the program. Because of the complaints, WE and the federal government decided to "part ways" leaving administration of the grant program to the federal government. At a press conference on 13 July 2020, Trudeau apologized for not recusing himself from cabinet discussions of the program. Ethics Commissioner Mario Dion's report confirmed Trudeau's assertion that Canada's civil service had recommended WE Charity to manage the Canada Student Service Grant program. The report exonerated Trudeau, but also found that finance minister Bill Morneau had "given WE preferential treatment by permitting his ministerial staff to disproportionately assist it when it sought federal funding.”	Justin Trudeau, Bill Morneau	2020
ArriveCAN app	Canada's ArriveCAN app was developed and introduced in April 2020 as a COVID-19 screening and communication tool requiring travelers entering Canada to upload their contact information, travel information and quarantine plans. The app was initially developed as a joint effort between the Canadian Border Services Agency (CBSA) and the Public Health Agency of Canada (PHAC) for $80,000. The app became mandatory to use for all travelers entering Canada in November 2020 and after a new version was launched in July 2021 its use was kept a compulsory public health screening requirement for all travelers entering Canada until October 1, 2022. There has been much scrutiny over how much this app cost to develop and who was subcontracted for its development. Contracts show that the federal government will spend close to $54 million with 23 separate subcontractors. A Parliamentary committee ordered federal departments to submit contracting documents related to the app but have been told that the names of subcontractors cannot be released citing issues of confidentiality. In July 2022 a glitch in the app erroneously instructed more than 10,000 travelers to quarantine. Over the Canadian Thanksgiving weekend (October 8 – 10, 2022) developers at two separate IT companies each developed duplicates of the ArriveCAN app in less than 2 days for an estimated cost of $250,000. On November 2, 2022, a motion was passed calling on the Auditor General of Canada to "conduct a performance audit, including the payments, contracts and sub-contracts for all aspects of the ArriveCan app, and to prioritize this investigation." This was the second such motion to pass.	Liberal Party, Marco Medicino, Bill Blair, Jean Yves Duclois	2022
Sister In-Law Ethic Commissioner	In 19 April 2023, Martine Richard, initially appointed as the interim ethics commissioner of Canada, resigned due to concerns over her familial ties to Dominic LeBlanc, the Intergovernmental Affairs Minister. Richard's appointment was criticized for potential conflicts of interest given her relationship to a cabinet minister. She had been part of the ethics commissioner's office since 2013, serving in a senior role before her brief tenure as interim commissioner was cut short by her resignation amid these concerns.	Martine Richard, Dominic LeBlanc	2023
Chinese government interference in the 2019 and 2021 Canadian federal elections	In late 2022, various media outlets around the world reported on a suspected attempt by the People's Republic of China to infiltrate the Parliament of Canada by funding a network of candidates, in majority liberals members, to run in the country’s 2019 federal election.	Government of China, CSIS, Liberal Party, Justin Trudeau, Han Dong, Vincent Ke, Conservative Party	2023
Yaroslav Hunka scandal	On September 22, 2023, during the visit of Ukrainian president Volodymyr Zelenskyy to the Parliament of Canada, Waffen-SS veteran Yaroslav Hunka was thanked for his service in the SS Division Galicia by Speaker Anthony Rota and praised as a Canadian and Ukrainian hero for fighting Russians. He received a standing ovation from House members, Justin Trudeau, Ukrainian president Volodymyr Zelenskyy and Germany's Ambassador to Canada Sabine Anne Sparwasser.	House of Commons, Justin Trudeau, Anthony Rota, Volodymyr Zelenskyy, Sabine Anne Sparwasser	2023
Poilievre "Wacko" comment	On April 30, 2024 Conservative Party Leader Pierre Poilievre called Prime Minister Justin Trudeau "a wacko Prime Minister" in the House of Commons resulting in the expulsion of Poilievre for the remainder of Question Period. Following the expulsion by Speaker Greg Fergus, the entire Conservative caucus walked out of the House of Commons chamber in protest. This culminated in further name-calling by Justin Trudeau who called Poilievre "spineless" which further resulted in Conservative MP Rachel Thomas being expelled from the House of Commons for personally attacking Speaker Fergus.
