[19] With increasing unemployment and continued housing and affordability issues, Miller initially said reducing immigration targets was not feasible but he later signalled there could be an adjustment coming in November 2024.

[23] He also called the insinuation the Liberal government dramatically increased immigration targets to secure votes in future elections, "political hooey".

[30] On October 24, 2024, after increasing immigration targets each year since taking power in 2015 (excluding the COVID pandemic), the Liberal government announced they were reducing the number of permanent residents by 20%, commencing in 2025.

[32][33] During the press conference, Miller claimed rent in Vancouver and Toronto had decreased since the government reduced the number of study permits by 43% the previous year.

[40] On August 14, 2024, Miller said he was "disgusted" with the case of Ahmed Fouad Mostafa Eldidi, who was made a citizen of Canada after he had beheaded someone on film when he was part of the terrorist group ISIS in 2018.

[41] Eldidi would have gone unnoticed until a tip from police in France notified the RCMP of a conspiracy to terrorize Canadians while the 2024 Paris Olympics were ongoing.

Eldidi and his son were apprehended with bombs at a hotel in Toronto on July 28 and charged with terrorism, possession of weapons and conspiracy to commit murder for the Islamic State.

[42] In October 2024, Miller defended the Prime Minister when some Liberal MPs expressed their concern over projected losses in the 2025 Canadian federal election if Trudeau remained in power.

[43] After Trudeau stepped down, Miller declined to run in the 2025 Liberal Party of Canada leadership election and chose to back candidate Mark Carney.

[44] Miller married Elin Sandberg, a former Swedish diplomat, whom he met at a party while both were studying at the Université de Montréal.
