One Tax Change that Could Improve Canada's Productivity and Benefit All

Why It Matters

Eliminating tax friction on reinvested gains could unlock dormant capital, raising productivity and fostering higher‑value investment across Canada’s economy.

Key Takeaways

• Canada lags US productivity by ~20% per hour
• Capital gains tax creates lock‑in, slowing asset turnover
• Broad deferral could unlock capital for productive reinvestment
• Estonia’s profit‑distribution tax model boosts reinvestment speed
• Conservatives and PM Carney support limited capital gains deferral

Pulse Analysis

Canada’s productivity gap has become a headline concern, with per‑capita GDP growth trailing the United States since 2015 and output per hour worked falling about 20 percent behind its biggest trading partner. The Bank of Canada’s recent "break the glass" warning underscores structural weaknesses, particularly in capital formation. While traditional policy levers have focused on labour and technology, tax‑induced frictions—especially the capital‑gains lock‑in—remain under‑addressed, trapping capital in legacy assets and dampening entrepreneurial dynamism.

The lock‑in effect arises because investors must pay tax on unrealised gains when they sell, prompting them to hold onto depreciating or low‑growth assets. Countries such as the United States, United Kingdom, Germany, and Ireland have introduced broad rollover provisions that allow gains to be deferred when proceeds are reinvested in qualifying assets. Estonia takes this further by taxing corporate profits only upon distribution, effectively encouraging firms to retain earnings and redeploy them rapidly. This model has yielded faster asset turnover, simplified compliance, and a vibrant start‑up ecosystem—outcomes Canada could emulate without copying Estonia wholesale.

Politically, the idea is gaining traction. The Conservative Party’s 2025 platform mentioned a limited capital‑gains deferral, and Prime Minister Mark Carney has publicly advocated for a tax system that supports dynamism through deferral mechanisms. A well‑crafted policy could target reinvestment into Canadian‑based productive assets, preserving revenue by taxing gains upon final withdrawal while unlocking capital for innovation, job creation, and higher‑value output. If implemented, such reform would not only address the immediate productivity shortfall but also lay the groundwork for sustained, inclusive economic growth.
