What/who are your sources? You seem to know what shareholders and metrolinx know.The closure you get to 2024 and no opening announcement the average citizens psychological mindset will start aggressively questioning whether this will really open in 2023. The stance right now publicly at least is that it will open this year i.e. 2023. That is the understanding what most citizens have. They have accepted that it is basically April now and this line will open within the next 6 months or so.
Clearly this is not the case as already confirmed internally by various stakeholders and is common knowledge within them.
