Legislation

Among the more significant pieces of legislation adopted in the 42nd Parliament was Bill C-14, passed with a free vote, as the government's response to Carter v Canada; it inserted the term "medical assistance in dying" into the Criminal Code and made provisions for adult Canadians to engage in the practice. Bill C-16 added "gender identity or expression" to the list of prohibited grounds of discrimination in the Canadian Human Rights Act and the list of characteristics of identifiable groups protected from hate propaganda in the Criminal Code – with only 40 Conservative Party members, who were all granted a free vote, opposed the bill. With all party support, the Accessible Canada Act (Bill C-81) created the Canadian Accessibility Standards Development Organization and the positions of Accessibility Commissioner as a member of the Human Rights Commission and Chief Accessibility Officer as an adviser to the minister responsible for accessibility. The Cannabis Act (Bill C-45) created a legal framework that allows for recreational use of cannabis by adults. Bill C-69 repealed and replaced the Canadian Environmental Assessment Act and the National Energy Board Act with the Impact Assessment Act and the Canadian Energy Regulator Act, respectively, and renamed the Navigation Protection Act to the Canadian Navigable Waters Act with new considerations for what constitutes 'navigable water'.

In modernizing existing legislation, the Transportation Modernization Act (Bill C-49) amended the Canada Transportation Act to, among other things, implement long-haul interswitching as a permanent mechanism in the rail industry, exclude revenue from interswitching and from the movement of grain in containers on flatcars from Canadian National Railway and Canadian Pacific Railway's maximum revenue entitlement,; require railway companies to keep up-to-date plans for each of their railway lines and to publicly report on their abilities to move a given summer's grain crop along with a winter contingency plans, raise the foreign ownership limits for Canadian airlines from 25% to 49% of an airline's voting interest with the new rule that no single foreign investor may own more than 25%, expand the review of joint ventures in the airline industry to also include the public interest and fair competition practices; the bill also amended several other transportation-related acts including the CN Commercialization Act to increase the individual ownership limit in Canadian National Railway from 15% to 25%, and the Railway Safety Act to require the installation of locomotive voice and video recorders onto trains. Bill C-23 repealed the Preclearance Act, 1999 and replaced it with the Preclearance Act, 2016 Bill C-59 modernized national security matters by adopting four new acts titled the National Security and Intelligence Review Agency Act, the Avoiding Complicity in Mistreatment by Foreign Entities Act and the Intelligence Commissioner Act and Communications Security Establishment Act, in addition to making amendments to the Canadian Security Intelligence Service Act, Security of Canada Information Sharing Act and Secure Air Travel Act. Bill C-25 variously amended the Canada Business Corporations Act, Canada Cooperatives Act, and Canada Not‑for‑profit Corporations Act to, among other things, allow more online tools to be used to disseminate required information to shareholders in notice and access systems, to require certain types of corporations to disclose to shareholders the composition of their boards and senior management, as well as their diversity policies or the statement that they do not have a diversity policy. The bill also prohibited businesses from issuing bearer forms of share certificates and share warrants and modified how directors of certain corporations and cooperatives are elected: that they must be elected individually, not as a slate or a group of candidates, and reduce maximum term lengths from 3 to 1 years. Bill C-57 updated how Canada's Sustainable Development Strategy is implemented. Bill C-78 updated the Divorce Act and two other related acts, as well as brought them in line with international standards of the Child Protection Convention and Child Support Convention.

On public safety and crime, Bill C-46 inserted new provisions into the Criminal Code regarding drug–impaired driving and the ability of peace officers to use drug screening equipment and random breath testing. On animal cruelty, Bill C-84 expanded the Criminal Code's provisions against cockpits to include any "arena for animal fighting" and in response to the Supreme Court of Canada findings in R. v. D.L.W., added a definition for bestiality.

Bill C-51 repealed or modified provisions within the Criminal Code found to be unconstitutional or obsolete, including those against dueling, blasphemous libel, witchcraft, crime comics and trading stamps and, in response to R v JA, clarified that an unconscious person is unable to grant consent to sexual activity.

Bill C-93 created a process in the Criminal Records Act to allow individuals convicted of possession of cannabis before its legalization to request a record suspension.

Responding to other legislation adopted during the previous parliament, Bill C-37, removed some of the obstacles to supervised injection sites that the previous parliament's Respect for Communities Act had put in place and replaced the previous government's National Anti-Drug Strategy with the new Canadian Drugs and Substances Strategy, mostly centered on the opioid epidemic.

Bill C-6 kept, but modified or expanded, Strengthening Canadian Citizenship Act's prohibition that time spent imprisoned does not contribute to the residency requirement, that an imprisoned applicant may not be granted citizenship, and that citizenship applicants must file tax returns during their residency requirement. In addition to adding a purpose statement to the Fisheries Act, Bill C-68 restored the provision against the harmful alteration, disruption or destruction of fish habitat that the Jobs, Growth and Long-term Prosperity Act had deleted. Bill C-4 repealed two private member bills adopted in the last parliament concerning union voting and financial reporting. Preparing for the 2016 Census, and in response to the previous government's involvement in the 2011 Census, Bill C-36 amended the Statistics Act to provide more independence to the Chief Statistician, remove imprisonment as a penalty for not responding to a census, and replacing the National Statistics Council with the Canadian Statistics Advisory Council. Bills C-17 and C-88 amended the previous parliament's Yukon and Nunavut Regulatory Improvement Act and the Northwest Territories Oil and Gas Operations Act, respectively, to address certain objections to the previous legislation. Bill C-62 restored or addressed changes made by the previous parliament to the Federal Public Sector Labour Relations Act regarding the determination of essential services, the ability to select between arbitration and conciliation to resolve collective bargaining disputes, and matters related to sick and disability leave.

Following through with international agreements, Bill C-11 implemented the Marrakesh VIP Treaty, Bill C-13 implemented the Bali Package, Bill C-64 implemented the Wreck Removal Convention, Bill C-82 implemented the BEPS multilateral instrument, and Bill C-31 implemented the Canada–Ukraine Free Trade Agreement, all with unanimous consent, while the Comprehensive Economic and Trade Agreement (Bill C-30) and the Trans-Pacific Partnership (Bill C-79) were implemented with only Liberals and Conservatives in support. Fulfilling a condition to ending Trump tariffs on steel and aluminum, Bill C-101 suspended, until 2021, the moratorium on trade safeguards. Further integrating the principles of the Declaration on the Rights of Indigenous Peoples, the Indigenous Languages Act (Bill C-91) created the Office of the Commissioner of Indigenous Languages to support the efforts of Indigenous peoples in maintaining Indigenous languages and Bill C-92 expanded the what is considered the best interests of an Indigenous child in the provision of child and family services to include the child's traditions, customs and language. With only Liberal Party support, Bill C-7 was adopted as the government's response to the Supreme Court's ruling in Mounted Police Association of Ontario v. Canada (Attorney General), allowing RCMP members to have certain collective bargaining rights. Bill C-22 created the National Security and Intelligence Committee of Parliamentarians. Bill C-58 amended the Access to Information Act to insert a new purpose statement, insert in requirements to make requests, allow bad faith or vexatious requests to be refused, and require proactive publication of certain information (e.g. travel expenses, hospitality expenses, etc.) Bill C-10 amended the Air Canada Public Participation Act to expand where Air Canada's maintenance centres may be located to the general provinces of Manitoba, Ontario and Quebec, rather than the specific cities of Winnipeg, Mississauga and Montreal. With only the Conservative Party and Bloc Québécois opposed, Bill C-50 created new reporting requirements for political fundraising events attended by a party leader or a minister and expanded the reporting of leadership campaign expenses.

Canadian Ministry

The 29th Canadian Ministry began with the 42nd Parliament and was sworn in by Gov. Gen. David Johnston on November 4, 2015. It was the first Cabinet of Canada to have an equal number of men and women. Prime Minister Trudeau appointed Bill Morneau to be Minister of Finance, Jody Wilson-Raybould as Minister of Justice and Attorney General of Canada, Jane Philpott as Minister of Health, Catherine McKenna as Minister of Environment and Climate Change, Harjit Sajjan as Minister of National Defence, and Ralph Goodale as Minister of Public Safety and Emergency Preparedness

The first change to the membership of the 29th Ministry occurred with the May 31, 2016, resignation of Hunter Tootoo as Minister of Fisheries, Oceans, and the Canadian Coast Guard so that he can sit as an independent MP; he was replaced by Dominic LeBlanc. The second change in membership came with the January 10, 2017, retirements of Foreign Affairs Minister Stéphane Dion and Immigration Minister John McCallum. The Prime Minister promoted Ahmed Hussen to replace McCallum at Immigration, and moved Chrystia Freeland from Minister of International Trade to Foreign Affairs, with François-Philippe Champagne being promoted to replace Freeland at International Trade. In that same cabinet shuffle MaryAnn Mihychuk was removed from cabinet and Karina Gould promoted to cabinet, with Patty Hajdu replacing Mihychuk as Minister of Employment, Workforce, and Labour, Maryam Monsef replacing Hajdu as Minister of Status of Women, and Gould taking over Monsef's role as Minister of Democratic Institutions.

An August 28, 2017, cabinet shuffle instigated by Judy Foote, Minister of Public Services and Procurement, resigning as an MP due to health concerns, saw Foote replaced by Minister of Sport and Persons with Disabilities Carla Qualtrough, with Kent Hehr becoming Sports minister and Seamus O'Regan being promoted to take over Hehr's role as Minister of Veterans Affairs. In that same cabinet shuffle Philpott moved to the newly created Minister of Indigenous Services with Ginette Petitpas Taylor being promoted to replace Philpott as Health minister. On January 25, 2018, Hehr resigned from cabinet following accusations of inappropriate behaviour and was replaced by Kirsty Duncan who added Hehr's role as Sports minister to her existing duties as Minister of Science.

A major cabinet shuffle on July 18, 2018, saw the promotion of five MPs to cabinet with duties within several ministries shifted around. Bill Blair had the Ministry of Border Security and Organized Crime Reduction created for him from duties split off of Ahmed Hussen's portfolio. Jonathan Wilkinson took over the Minister of Fisheries, Oceans, and the Canadian Coast Guard role from Dominic LeBlanc who became Minister of Intergovernmental Affairs, Northern Affairs and Internal Trade, with Intergovernmental Affairs coming from Trudeau's own portfolio and Northern Affairs from Carolyn Bennett's. Pablo Rodríguez took over the Ministry of Canadian Heritage from Mélanie Joly who had the role of Minister of Tourism, Official Languages and La Francophonie created for her, taking La Francophonie from Marie-Claude Bibeau and Tourism from Bardish Chagger's portfolio. While Chagger remained Leader of the Government in the House of Commons her responsibility for Small Business went to Mary Ng who became Minister of Small Business and Export Promotion. Filomena Tassi became the Minister of Seniors, split out of Jean-Yves Duclos portfolio. Jim Carr took over Minister of International Trade Diversification from François-Philippe Champagne who took over as Minister of Infrastructure and Communities from Amarjeet Sohi who took over Carr's role as Minister of Natural Resources.

A shuffle on January 14, 2019, instigated by the resignation of Scott Brison, President of the Treasury Board, saw Jane Philpott move from Minister of Indigenous Services to replace Brison, with Seamus O'Regan filling her former position and Jody Wilson-Raybould replacing him as Minister of Veterans Affairs. Both David Lametti and Bernadette Jordan were promoted to cabinet from parliamentary secretary roles; Lametti to replace Wilson-Raybould as Minister of Justice and Attorney General and Jordan to fill the new role of Minister of Rural Economic Development. Amidst the SNC-Lavalin affair Wilson-Raybould and Philpott resigned their cabinet positions and were replaced by Lawrence MacAulay and Joyce Murray, respectively, with Marie-Claude Bibeau taking over MacAulay's former role as Minister of Agriculture and Maryam Monsef adding Bibeau's International Development duties to her existing duties as Minister of Status of Women.

Senate

At the beginning of the 42nd Parliament, the senate consisted of 83 members, 47 of which caucused with the Conservative Party and 29 with the Senate Liberal Caucus. Of those who left the Senate during the 42nd Parliament, 18 had reached the mandatory retirement age, including 10 Conservatives and the last remaining senator appointed by Pierre Trudeau, and 11 voluntarily resigned, including 7 Liberals. One senator (Tobias Enverga) died while in office. The new Prime-Minister's first appointment to the senate was, in March 2016, Peter Harder to act as the Government Representative. To move the senate towards more independence, the Prime-Minister established the Independent Advisory Board for Senate Appointments to provide merit-based recommendations. Based on their first set of recommendations, Premier Trudeau appointed 6 new senators in April, including chairman of the Truth and Reconciliation Commission Murray Sinclair, former NDP provincial minister Frances Lankin, journalist André Pratte, Paralympian Chantal Petitclerc, and academics Raymonde Gagné and Ratna Omidvar. In the meantime, between November 2015 and March 2016, four Conservative, two Liberals and the last remaining Progressive Conservative senator had changed their party standing to non-affiliated. A further three Senate Liberals and one Conservative went independent between April and July, before the Prime-Minister appointed the next set of senators in November, 17 in total, based on the recommendations of the Independent Advisory Board, and all of whom sat as "non-affiliated". These senators included Éric Forest, bankers Sabi Marwah and Lucie Moncion, police commissioner Gwen Boniface, academics or doctors Yuen Pau Woo, Wanda Thomas Bernard, Diane Griffin, Marie-Françoise Mégie, Harvey Chochinov, art historian Patricia Bovey, lawyers Marilou McPhedran, Renée Dupuis, Marc Gold, former public servants Tony Dean, Howard Wetston, Raymonde Saint-Germain, and artist René Cormier. Also during that time, the Independent Senators Group was founded, in March 2016, as a non-partisan parliamentary group and on December 2, 2016, 33 non-affiliated members joined to form inaugural membership of Independent Senators Group. Trudeau appointed two more senators, Rosa Galvez and Daniel Christmas, in December 2016 and three in all of 2017, Mary Coyle, dentist Mary Jane McCallum and writer David Adams Richards, all of whom joined the Independent Senators group. Also in 2017, the Independent Senators Group took over the majority of the senate, though they did not vote as a block, with 37 members in October, from the Conservative Party who had 36 members. Throughout 2018, a further 19 senators were appointed, all of whom caucused with the Independent Senators Group, including teacher Martha Deacon, lawyers Yvonne Boyer, Pierre Dalphond and Josée Forest-Niesing, doctor Mohamed-Iqbal Ravalia, interim RCMP Commissioner Bev Busson, journalists Paula Simons and Julie Miville-Dechêne, and former Yukon Premier Pat Duncan.
