I'll start, and then I'll invite Scott to add briefly.
To reimburse mileage rates we use the National Joint Council commuting assistance, which actually does take into account cost drivers such as inflation. We are in the process now of doing a review of the medical transportation benefit with the Assembly of First Nations. We made a change last year, for example, by increasing by 25% meal and accommodation rates in response to calls that we hadn't sufficiently increased our rates for a number of years.
I'll invite Scott to speak to anything that's more specific to the medical taxi issue.
