In yet another high-stakes maneuver in the fall session of Parliament, the Bloc Québécois recently tabled a motion urging the Trudeau government to support Bill C-319, which would increase Old Age Security (OAS) payments for seniors aged 65 to 74 by 10 per cent. The motion passed and the Bloc is threatening to trigger an election if the Trudeau government doesn’t give the bill final approval before October 29.

Meanwhile, according to a new poll, 79 per cent of Canadians “support or somewhat support” the OAS increase. But crucially, the poll provided no information to respondents about the costs associated with expanding OAS, even though Canadians should understand the costs before they pledge support for any government program.

Consider this—according to past polling, more than two-thirds of Canadians expressed support for the Trudeau government’s national dental care, $10-a-day daycare, and pharmacare programs. Yet once respondents were made aware of potential tax increases (specifically, increases to the GST), support plummeted to less than 50 per cent for all three programs.

Clearly, support for government programs can change dramatically once Canadians understand the costs since they ultimately must pay those costs. So, that being said, what are the costs of a 10 per cent increase in OAS payments for seniors aged 65 to 74?

According to the Parliamentary Budget Officer Yves Giroux, the policy would cost more than $3 billion a year, with a five-year price tag of $16.1 billion—a “significant chunk of change” in his words.

Based on its latest budget, the Trudeau government expects to run deficits of at least $20.0 billion for the next five years and rack up more than $400 billion in new debt by 2028/29. If the government borrows more money to pay for increased OAS benefits, that debt number will grow even larger.

And again, Canadians will ultimately bear the costs of an expanded OAS through higher taxes in the future because Canadians must pay interest on government debt. This fiscal year (2024/25) federal debt interest costs are already expected to reach $54.1 billion—which is equal to the entire amount raised by the GST. These are taxpayer dollars that won’t go towards any services or programs for Canadians, and interest costs will continue to grow as the government adds more and more debt.

Finally, in addition to being costly, the plan is poorly targeted. While some programs such as the Guaranteed Income Supplement (GIS) provide additional income support to low-income seniors, OAS provides support to many upper middle-income seniors. Indeed, based on current thresholds, individual seniors (aged 65 to 74) earning up to $148,451 per year are eligible to receive OAS (though seniors earning more than $90,997 of income don’t receive the full amount). Therefore, if Bill C-319 becomes law, a senior couple with a combined household income of nearly $300,000 will receive an increase in their OAS payments.

Increasing OAS payments will cost billions each year while supplementing the income of many seniors who aren’t in need. Despite the political theatre in Ottawa, Canadians are ultimately the ones who will foot the bill.
