Legislation and motions 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 Bill C-69 repealed and replaced the Canadian Environmental Assessment Act and the National Energy Board Act with the Impact Assessment Act and the Canadian Energy Regulator Act,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'.

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.

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-75, generally seeking to address court delays and promote fair and efficient trails but also included multiple other amendments, removed the allowance of peremptory challenge, allowed warrants to be acted upon anywhere in Canada rather than only in its originating province, added new provisions for videoconference by judges and court participants, restricted the use of preliminary inquiries to only cases involving offences punishable by life imprisonment, reclassified an additional 115 offenses as hybrid offenses so that they may be prosecuted either as summary convictions or as indictable offences, increased the maximum penalty for summary convictions to two years imprisonment, and deleted or amended offenses from the Criminal Code that the Supreme Court found to be unconstitutional (abortion in R v Morgentaler, vagrancy in R v Heywood, spreading false news in R v Zundel, anal intercourse in R v CM, and those offenses in R v Martineau). 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.
