The only thing Canada can do is send observers who would be on site and work with the Independent National Electoral Commission, CENI, to ensure that there really is transparency in the counting of votes and publishing of the results and to ensure that Mr. Kabila does not run for president because he has used up his two mandates. In compliance with the Congolese constitution, he is not entitled to a third mandate. In addition, of course, voting machines should no longer be used.
With all that, we would have an 80% chance of a fair and transparent election.
