I can't find any support for that contention:

Nonetheless, the increase in per-person spending is egregious, and is the inescapable outcome of a self-involved and unaware people when led by a narcissistic unserious buffon like Trudeau.

Justin Trudeau’s legacy—record-high spending and massive debt
The government ran nine consecutive deficits including a $61.9 billion deficit last fiscal year.

Opinion: Mark Carney was right: He’s not Justin Trudeau. He spends more
Ottawa's recently released Main Estimates show spending up, with 26 agencies and departments increasing 20 per cent or more. Find out more

Turns out I can't find anything to solifidy the claim either, but I remember it being big news when it was first announced.
I am fairly certain it had to do with Trudeau & Freeland doubling our national debt. So the debt that had accumulated over approx 156 years, they managed to double that debt in a mere 8 years...hence the assertion that he did in fact spend more than all previous PM's combined. (Accounting can be a tricky business, so maybe I'm off....but nonetheless, like you said, unacceptable.)

Here is the AI overview (still getting used to this whole AI thing, so please forgive me for not including a link)
While many Canadian governments have increased the national debt, Sir Robert Borden's government (1911-1920), particularly during World War I, increased per-person debt levels the most due to the war and subsequent economic downturns. Justin Trudeau's government also significantly increased debt, becoming the only prime minister since 1900 to increase per-person debt during a period without a major war or economic downturn.
Here's a more detailed breakdown:
- Sir Robert Borden (1911-1920):
Borden's government saw the largest increase in per-person debt due to the high costs of World War I and the economic challenges that followed.
- Justin Trudeau (2015-Present):
While Trudeau's government did not face a major war or recession initially, it increased spending and debt levels, particularly during the COVID-19 pandemic. He is the only prime minister since 1900 to increase per-person debt without a war or significant economic downturn.
- Other notable periods of debt accumulation:
Other periods of significant debt increases include the tenures of William Lyon Mackenzie King (1935-1948) and during the 1990s recession.
- Factors influencing debt:
It's important to note that debt levels can be affected by global events like wars and economic downturns, as well as government spending decisions.
