Answer from Metrolinx: Metrolinx is committed to working with the Ontario Heritage Trust on all steps of the archaeological process as well as a heritage interpretation and commemoration plan for the entire First Parliament site.
Some excavation will be required on this site to support construction of the future Corktown Station. However, no construction activity will begin until all archaeological assessments are completed, including uncovering any archaeological features or artifacts that may be present. Wherever possible, Metrolinx will strive to conserve these features in the places they are found.
All archaeological work will be done according to the standards and guidelines laid out by the Ministry of Heritage, Sport, Tourism and Culture Industries and all plans will be reviewed and approved by the Ministry before any archaeological work begins.
