He left to Boston and then rode to Montreal where he arrived near midnight on 30 August 1912 at the Windsor train station on Peel Street and was greeted by William Sutherland Maxwell. He would stay in Montreal until 9 September. On his first day in the city he was visited by Frederick Robertson Griffin who would later lead the First Unitarian Church of Philadelphia. Later that morning he visited a friend of the Maxwell's who had a sick baby. In the afternoon he took a car ride around Montreal. That evening a reception was held including a local socialist leader. The next day he spoke at a Unitarian church on Sherbrooke Street. Anne Savage recorded that she had sought him out but uncharacteristically was shy upon seeing him. He took up residence in the Windsor Hotel. The next day William Peterson, then Principal of McGill University visited him. After a day of meeting individuals he took an afternoon excursion on his own possibly to the francophone part of the city and back. That evening he spoke to a socialist meeting addressing "The Economic Happiness of the Human Race" — that we are as one family and should care for each other, not to have absolute equality but to have a firm minimum even for the poorest, to note foremost the position of the farmer, and a progressive tax system. The next day he rode the Mountain Elevator of Montreal The next day Paul Bruchési Archbishop of the Roman Catholic Archdiocese of Montreal visited him and later he spoke at the Saint James United Church; his talk outlined a comprehensive review of the Bahá'í teachings. Afterwards he said:I find these two great American nations highly capable and advanced in all that appertains to progress and civilization. These governments are fair and equitable. The motives and purposes of these people are lofty and inspiring. Therefore, it is my hope that these revered nations may become prominent factors in the establishment of international peace and the oneness of the world of humanity; that they may lay the foundations of equality and spiritual brotherhood among mankind; that they may manifest the highest virtues of the human world, revere the divine lights of the Prophets of God and establish the reality of unity so necessary today in the affairs of nations. I pray that the nations of the East and West shall become one flock under the care and guidance of the divine Shepherd. Verily, this is the bestowal of God and the greatest honor of man. This is the glory of humanity. This is the good pleasure of God. I ask God for this with a contrite heart.
