Thank you very much for your questions, Mrs. Vignola.
The report you were referring to indicates that $12 billion has not been spent in the federal health portfolio. As has been said, this is related to uncertainty arising from COVID‑19.
Another $4.3 billion is for settlements with indigenous peoples, but it's impossible to know when they will be ratified by the communities. So that's part of the reason for the lapsed funds.
A third example is the reprofiling of $5.2 billion related to infrastructure projects. This may be due to delays in completing some projects, because the construction season in the north is so short that it's impossible to finish all projects planned.
Implementation delays are a fourth consideration. Indigenous Services Canada is a good example, because it has not spent all of its allocated funds due to its staff being unable to travel to communities.
The final consideration would be the Treasury Board's central votes, $1.8 billion in total. When these funds go unused, they are lapsed. If they are still needed, then they must be requested from Parliament again.
To sum up, we have $12.1 billion for COVID‑19, $4.3 billion for indigenous peoples, $5.2 billion for delays and infrastructure, $5.5 billion for implementation delays, and $1.8 billion for central votes.
