There is a serious problem with letting CDPQ Infra operate a downtown line, which is that they couldn't agree on a revenue sharing agreement with the ARTM. A new downtown line is fine, but if it means insufficient funding for the already underfunded metro system, it's not clear it would actually be a net benefit. Ultimately the problem is the legislation around the ARTM having to be able to be long-term profitable, which means that such a project can't make sense. As far as I'm aware, the ARTM and the city also agreed with a plan where the REM de l'est would connect somewhere onto the green line to avoid competing with downtown metro service, but that was rejected by CDPQ Infra as unprofitable.
