What productivity is, and why it is the whole game
Productivity is how much you get out for each hour you put in. It sounds like an accounting term, but over a long enough period it is the only thing that raises living standards. Wages, pensions, hospital budgets and house prices all eventually run into the limit of how much the country produces per hour.
Canada's problem is not that people work less. Canadians work about as many hours as Americans. The problem is that each hour produces less, and the gap is now around 25 to 30 percent depending on how you measure it. Over a working life that compounds into a large difference in income.
The usual suspects
Economists have a list. Canadian businesses invest less in machinery, software and research per worker than American ones do. The country has a lot of small firms that stay small, partly because of tax rules that reward staying under thresholds. Interprovincial trade barriers make the domestic market smaller than it looks. And a large share of the economy is in sectors like real estate and construction that do not get more productive quickly.
The last one is uncomfortable, because it means the housing boom that made a lot of people feel rich was also pulling capital away from the things that would have made the country richer.
What AI could actually do
The optimistic story goes like this: most Canadian workers are in services, services productivity is hard to raise, and AI is the first technology that directly raises the output of a person sitting at a desk. Early studies of customer service agents and programmers using AI tools found productivity gains in the range of 15 to 40 percent on the tasks measured, with the biggest gains for the least experienced workers.
The sceptical story is that we have heard this before. Computers showed up in every office in the 1980s and productivity statistics did not move for a decade. Robert Solow's line from 1987 still applies: you can see the computer age everywhere but in the productivity statistics. Technology only shows up in the numbers when businesses reorganise around it, and Canadian businesses have been slow to reorganise around anything.
My read
AI raises the ceiling. It does not change the habits that keep Canadian firms below the ceiling. If a company would not buy software in 2019, it is not going to redesign its workflow around a language model in 2026 because a central banker used the word emergency.
So the fix is boring. Tax rules that stop punishing growth, a real single market inside the country, and public procurement that buys from young firms. AI makes every one of those reforms pay off faster. It does not replace them. Anyone who tells you the productivity gap closes on its own because the tools got better is selling something.
