Cut-and-Cover Option for Yonge North Subway Extension

Controversy continues in York Region over the routing of the proposed Yonge North Subway Extension (YNSE). The preferred option from Metrolinx is Option 3A, which involves deep tunneling below 60 homes to reach a surface station at the GO line (“Bridge Station”). Both Markham and Vaughan Councils have voted against Option 3A.

In April, Transport Action Ontario submitted an alternative – Option 2A, involving cut-and-cover across vacant lands. Metrolinx is evaluating this option. We have now supplemented our proposal by also recommending cut-and-cover under the northern portion of Yonge St. This offers cost savings and simplifies the elevation transition from a tunnel under Yonge St to a surface station at the GO line. Metrolinx has indicated they will evaluate this option.
