Maximum fees for Aggregate Mining and Transportation change based on changes in Manitoba’s consumer price index (CPI) with 2021 as reference year.
Consumer Price Index, Annual Monthly Average, Manitoba, 2021:
142.0
Consumer Price Index, Annual Monthly Average, Manitoba, 2025:
164.6

You can see this CPI information at the following link, ensuring the data is narrowed to Manitoba.
Consumer Price Index, annual average, not seasonally adjusted (statcan.gc.ca)

To calculate the change between these two numbers, divide CPI in previous year by CPI in 2021 as follows:
CPI Multiplier = 164.6 ÷ 142.0 = 1.159

To determine current maximum fees, multiply 2021 fees (in $) by the change in CPI (above), as follows, to the thousandth:
2021 Fees x (CPI Multiplier) = Current Fees

The results of this formula show the new fees as follows:
