Here's a comprehensive list of key achievements by Prime Minister Mark Carney of Canada, in the first 5 months in office.

DOMESTIC POLICY & ECONOMIC MEASURES

Carbon Pricing & Tax Relief

Terminated the consumer carbon tax, effective April 1, 2025, while still issuing the April carbon rebate as scheduled.

Introduced a bottom marginal income tax cut from 15 % to 14 %, saving a typical two-income household about C$840 per year.

Proposed a temporary GST exemption for first-time homebuyers.

Spending and Efficiency

Announced a government-wide initiative to reduce operational spending by 15 % by 2029.

Pushed infrastructure and economic resilience in response to US trade tensions, expediting major domestic projects after denouncing U.S. tariffs as "unlawful."

Immigration Reform

Launched the Immigration Levels Plan 2025–2027, reducing annual permanent resident targets to ~395,000 (2025), ~380,000 (2026), and ~365,000 (2027)—down from prior highs.

Energy & Environmental Initiatives

Supported a new oil pipeline to the West Coast and a proposed C$16.5 billion carbon capture system for Alberta’s oil sands.

Backed an existing EV sales mandate aiming for 20 % of sales by 2026 and 100 % by 2035.

Labour

Abolished the Minister of Labour role, transferring responsibilities to the Minister of Jobs and Families.

During the Air Canada flight attendants strike (August 2025), directed back-to-work arbitration, leading to a tentative agreement with pay improvements.

INFRASTRUCTURE & TRADE

Internal Trade Reform

Passed Bill C-5 – the One Canadian Economy Act, removing federal barriers to interprovincial trade and streamlining nation-building approvals.

Infrastructure Investment

Backed billions in investments—from the Plan to Build, housing funds, health infrastructure, to critical minerals support, although specifics pre-date his exact tenure.

Arctic Security & Defense

Approved a C$6 billion Over-the-Horizon Radar purchase from Australia and committed C$420 million to improve Arctic military presence.

Defense & Foreign Policy

NATO & Military Spending

Announced the largest defense spending increase since WWII, adding C$9.3 billion to meet the NATO 2 % GDP target this year—exceeding timelines by seven years.

Ukraine Support

Made a surprise visit to Kyiv on Ukrainian Independence Day—his first in a conflict zone—and reaffirmed support for Ukraine alongside President Zelenskyy.

Announced C$2 billion in military aid plus a C$2.3 billion loan to Ukraine.

Invited Zelenskyy to the G7 Summit in Alberta, elevating diplomatic support.

G7 Leadership

Hosted and chaired the 51st G7 Summit in Kananaskis, Alberta (June 2025), bringing in global leaders including India’s Modi and Ukraine’s Zelenskyy.

Global Diplomacy & Mineral Strategy

During his European tour, announced a German-Norwegian finalist for Canada’s submarine procurement, signed a critical minerals cooperation declaration with Germany, and mobilized nearly C$500 billion in energy, port, and digital infrastructure investments.

Concurrently, in Germany he pushed defense and automotive mineral partnerships; in Kyiv, packaged military aid; and elsewhere emphasized Canada’s NATO commitments.
