The Ontario Line’s estimated cost has tripled since the project’s 2019 plan, with Metrolinx reporting a substantially higher price tag and expecting further increases. City News Toronto reports that initial estimates were about $10.9 billion in 2019, rising to nearly $20 billion by 2022, and to roughly $29 billion by June, according to Metrolinx’s State of the Network report.
Global News (Canada) and The Globe and Mail report that Metrolinx CEO figures currently place the overall cost at about $34 billion so far. Both outlets note that this level remains well above the government’s original projection and that the final total will be higher than the current estimate. The accounts differ primarily in the specific milestone figures highlighted, ranging from earlier estimate updates (such as June’s State of the Network figure) to the more recent total cited by the CEO.
Overall, the sources agree that costs have risen sharply over time and that the latest estimates indicate the Ontario Line will cost substantially more than originally planned, with final costs not yet fixed.
