Senate From his appointment, Dalphond sat as a member of the Independent Senators Group. On May 21, 2020, Dalphond joined the Progressive Senate Group. His addition to the caucus brought the PSG's caucus to nine, and restored its official status.

Dalphond announced his intention to oppose use of the Emergencies Act during the "Freedom Convoy" protests, suggesting that it was a violation of section 8 of the Canadian Charter of Rights and Freedoms, which relates to "unreasonable search and seizure." On January 16, 2026, the Federal Court of Appeal ruled that the federal government's decision to invoke the Emergencies Act was unreasonable and ultra vires, and that related regulations and an economic order infringed paragraph 2(b) and section 8 of the Canadian Charter of Rights and Freedoms.
