Seaspan hasn't received anything; they funded that all internally.
Irving got a forgivable, interest free loan from the province, which pissed a lot of people off, but was technically in the rules, which was there was no federal funding for the upgrades.
Because it was supposed to be funded by the profits, the shipyards got some guarantees on the work packages, which basically had a penalty to pay them back for the modernization investments if the expected profits from the builds weren't realized because ships were cut. That's why a replacement for Polar in the non-combat package was put in, as otherwise we would have paid out a partial penalty.
If Davie gets something from the QC provincial level, that would be similar to Irving, but if they get federal funding that would be a massive change from the existing Umbrella agreements from the initial contract.
