I think you're referring to a report I did that looked at changes in provincial deficits in the first two years of the pandemic.
Certainly, for this last year—the 2021-22 fiscal year that's wrapping up in a couple of days—the projected provincial deficits, initially, were $70 billion. In this report's final estimate, they were about $20 billion, which is a huge change in how big the provincial deficits were. Six out of 10 provinces are likely to be in a surplus position this year or next year, largely due to an unforeseen recovery in economic growth in the fall, as well as unanticipated additional transfers from the federal government—although it was economic growth that largely drove this.
This additional revenue received by the provinces, in the neighbourhood of $60 billion over what they initially budgeted for in the 2021-22 fiscal year, is due to economic growth, but it's also due to higher inflation. Higher inflation benefits provincial as well as federal revenues insofar as those revenues stay relatively constant as a percentage of GDP. If nominal GDP goes up, whether due to inflation or real growth, you see more revenues as a result. So it was certainly partially due to increased inflation over the course of the fall.
