I would add that transportation logistics under COVID-19 in particular have been a real challenge. For charter flights, particularly where a number of workers aren't able to board the flight due to pre-departure testing, the cost of individual tickets can double or triple. This is all borne by the employer without any available support. Similarly, if you are quite a distance from an approved port of entry, the cost to get your workers to your operation is also done through private means and it can be quite expensive.
We've seen a continued rise in incremental costs throughout the pandemic and have not seen that reflected in the mandatory isolation support program.
