[8][9] During the mid-19th century, workers constructing the Victoria Bridge across the St. Lawrence River discovered a mass grave in Windmill Point where victims of the typhus epidemic of 1847 had been quarantined in fever sheds.
[17] From a decision made by some in February 1900,[18] and despite disagreement on consensus published in March 1900,[19] in December 1900 the monument was moved by Grand Trunk Railway.
[20][21] On December 18, 1901 the Grand Trunk Railway was requested by the delegates of the Irish societies to remove their tracks from the cemetery where the stone previously rested.
[24] In 1911 a judgment made by Mr. Justice Mabee declared Canada was large enough for public utility corporations to carry on their business without desecrating graves, and told the Grand Trunk Railway to install an iron fence and then have the stone returned.
[30][31][32] The Black Rock continues to be a significant icon, particularly within the Montreal Irish community led by the Ancient Order of Hibernians Canada.
Each year at the end of May, on the Sunday, the Canadian Irish community hosts a walk from St. Gabriel's church in Pointe St. Charles to the stone to commemorate those lives that were lost.
