The Commissioner of Canada Elections announced Thursday that Bowers had been charged with three counts.
The charges relate to allegations of taking illegal contributions from corporations and discounted airfares for Penashue's campaign in the general election that year.
Penashue won the race in the riding of Labrador, a breakthrough for the Conservative Party of Canada in an area that has traditionally voted Liberal.
After an extensive CBC News investigation into the financing of that campaign, Penashue resigned and ran in a subsequent 2013 byelection. He lost, however, to Liberal Yvonne Jones.
