Among the more significant pieces of legislation adopted in the first session was Bill C-14, the government's response to Carter v Canada (Attorney General), which inserted the term "medical assistance in dying" into the Criminal Code and made provisions for adult Canadians to engage in the practice.[3] Introduced by the Minister of Justice, Bill C-14 was passed with a free vote for both Liberal and Conservative party members. The Minister of Justice also introduced Bill C-16 which 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 - only 40 members opposed the bill, all from the Conservative Party who were granted a free vote. Bill C-45, the Cannabis Act, created a legal framework that allows for recreational use of cannabis by adults and 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.

Responding to legislation adopted during the previous parliament, Bill C-37, sponsored by the Minister of Health and opposed only by the Conservative Party, removed some of the obstacles to supervised injection sites that the previous parliament's Respect for Communities Act had put in place and the bill replaced the previous government's National Anti-Drug Strategy with the new Canadian Drugs and Substances Strategy, mostly centered on the opioid epidemic.[4] The Minister of Immigration, Refugees and Citizenship's Bill C-6 amended or repealed parts of the previous parliament's Strengthening Canadian Citizenship Act including the ability to revoke citizenship based on national security, the requirement that applicants for citizenship aged 14 to 18 and 55 to 64 to prove adequate knowledge Canada and of an official language, the residency requirement increase from 3 years to 4 years, the disallowance of time spent as temporary resident as contributing to the residency requirement, and the condition of citizenship that the applicant must intend to reside in Canada. 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. 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. Bill C-17 made amendments to the Yukon Environmental and Socio-economic Assessment Act to address the previous parliament's Yukon and Nunavut Regulatory Improvement Act and the subsequent court case that ensued.

The Preclearance Act, 2016 (Bill C-23) repealed and replaced the Preclearance Act, 1999 with a modernized version based on the Canada—U.S. Shared Vision for Perimeter Security and Economic Competitiveness.[5] The Transportation Modernization Act (Bill C-49) made numerous changes resulting from the review launched in 2014 of the Canada Transportation Act and the subsequent "Transportation 2030" plan, as well as the results of the previous parliament's Fair Rail for Grain Farmers Act, and the changes included implementing long-haul interswitching as a permanent mechanism in the rail industry; excluding revenue from interswitching and from movement of grain in containers on flat cars from Canadian National Railway and Canadian Pacific Railway's maximum revenue entitlement; requiring the 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; installation of locomotive voice and video recorders onto trains; increasing the individual ownership limit in Canadian National Railway from 15% to 25%; raising the foreign ownership limits for Canadian airlines from 25% to 49% of an airlines' voting interest with the new rule that no single foreign investor may own more than 25%; expanding the review of joint ventures in the airline industry to also include the public interest, as well as fair competition practices.[6] The Minister of Innovation, Science and Economic Development introduced Bill C-25 which amended the Canada Business Corporations Act and Canada Cooperatives Act to allow more online tools to be used to disseminate required information to shareholders in their 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 from issuing share certificates and share warrants in bearer form 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.

Following through with international agreements, Bill C-11 implemented the Marrakesh VIP Treaty,[7] Bill C-13 implemented the Bali Package and Bill C-31 implemented the Canada–Ukraine Free Trade Agreement, all with unanimous consent, while Bill C-30 implemented the Comprehensive Economic and Trade Agreement with only the Liberal and Conservative parties supporting. The Expungement of Historically Unjust Convictions Act (Bill C-66) allows the Parole Board of Canada to expunge historical convictions related to gross indecency, buggery or anal intercourse.[8] 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.[9] The Minister of Transport introduced Bill C-10 which 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, as well as clarifying what constitutes "maintenance".

Financial measuresEdit

Regarding financial measures, Bill C-2 amended the Income Tax Act to lower federal tax paid on income between $45,283 and $90,563 from 22% to 20.5% and introduce a new top tax bracket that applies a rate of 33% to a person's income in excess of $200,000.[10] The bill also re-instated the $5,500 annual limit to Tax-Free Savings Account contributions which the previous parliament had raised to $10,000. Bill C-26 amended the Canada Pension Plan to create the Additional Canada Pension Plan Account and to increase the maximum level of pensionable earnings.

The legislative changes resulting from the 2016 budget were implemented in Bill C-15 and Bill C-29 and included replacing the Canada Child Tax Benefit and Universal Child Care Benefit with the Canada Child Benefit, repealing the Family Tax Cut (income splitting) Credit, Education Tax Credit, Textbook Tax Credit, Children's Arts Tax Credit, Child Fitness Tax Credit, creating the School Supplies Tax Credit, exempting insulin pens, intermittent urinary catheters and feminine hygiene products from GST/HST, allowing a charity or athletic association to hold up to 20% interest in a limited partnership business, and expanding the definition of "Canadian exploration expense" to include environmental studies and community consultations conducted as a condition of obtaining a licence or permit. The Canadian Forces disability award and death benefit were raised to $360,000; the rates for Northern Residents Deduction were increased by 33%; and employment insurance benefits were temporarily extended for high unemployment areas (e.g. the northern areas of the provinces of Ontario, Manitoba, Saskatchewan and BC, the cities of Sudbury and Whitehorse, and most of the provinces of Alberta and Newfoundland and Labrador). Bill C-15 also repealed the previous parliament's Federal Balanced Budget Act and rolled back its age eligibility for the Old Age Security pension and Guaranteed Income Supplement from 67 to 65 years old.

The legislative changes resulting from the 2017 budget were implemented in Bill C-44 and Bill C-63. Among the changes was the phasing out of the Canada Savings Bond program, making commercial ride-sharing services subject to GST/HST, exempting naloxone from GST/HST, eliminating of the Public Transit Tax Credit and Investment Tax Credit for Child Care Spaces but extending the Mineral Exploration Tax Credit by one year, eliminating the GST/HST rebate for non-residents using Canadian accommodations as part of a tour package, increasing the excise tax on tobacco products and tying increases of the excise tax on alcoholic products to the consumer price index, and allowing mark-to-market accounting to be used for income tax calculations in forward rate and swap agreements.[11] Bill C-44 included, within it, the Canada Infrastructure Bank Act to invest directly or attract private investment in infrastructure projects that are anticipated to generate revenue and be in the public interest, and the Invest in Canada Act which created the new crown corporation called Invest in Canada Hub to promote foreign direct investment and created the Service Fees Act to replace the User Fees Act.[12] Bill C-63 included, within it, the Asian Infrastructure Investment Bank Agreement Act so Canada could join the Asian Infrastructure Investment Bank, repealed the Timber Marking Act, and created the Canadian Free Trade Agreement Implementation Act to replace the Agreement on Internal Trade Implementation Act.

Private member billsEdit

Nine private member bills received royal assent, with only Bill C-210 not receiving unanimous support:

Senate billsEdit

On behalf of the government, senate government bills included the Strengthening Motor Vehicle Safety for Canadians Act (Bill S-2) which amended the Motor Vehicle Safety Act to allow the Minister of Transport to order a motor vehicle company to issue a recall, rather than allow the process to be at the manufacturer's discretion; Bill S-3 which amended the Indian Act as the government's response to a Quebec Superior Court ruling finding sex-based inequities in the Indian Register to be contrary to the Charter of Rights and Freedoms; Bill S-4 which implemented conventions with Israel and Taiwan regarding the avoidance of double taxation and the prevention of income tax evasion; and Bill S-5 renamed the Tobacco Act to the Tobacco and Vaping Products Act[13] and introduced provisions relating to vaping products, such as a prohibition to selling or marketing to minors, plain packaging requirements and restrictions on advertising. Among the other bills initiated in the senate that were adopted by the parliament, Bill S-208 made May 20 of each year National Seal Products Day,[14] Bill S-211 made June 19 of each year National Sickle Cell Awareness Day, Bill S-218 made October of every year Latin American Heritage Month, Bill S-232 made May of every year Canadian Jewish Heritage Month, and Bill S-236 simply states Charlottetown is the birthplace of Confederation. Other senate public bills included the Justice for Victims of Corrupt Foreign Officials Act (Sergei Magnitsky Law) (Bill S-226) which allows the Governor-in-Council to seize property situated in Canada of a foreign national believed to be involved in extrajudicial killings or violations of internationally recognized human rights, and the Journalistic Sources Protection Act (Bill S-231) which allows journalists to object to an order to reveal a source of information and have the objection weighed by a court judge in light of public interest and rights to privacy. The Genetic Non-Discrimination Act (Bill S-201) was adopted with the Conservative Party, NDP and Green Party in favour; Liberal Party members were granted a free vote though the prime-minister urged members to oppose the bill, as presented, based on concerns of inconsistency with the constitution.[15] The act makes it a criminal offence to require an individual to undergo a genetic test, or to disclose the results of such a test, as a condition of providing goods or services, with exceptions for health care practitioners and researchers.

Canadian MinistryEdit

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[16] 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.
