My maternal grandfather came to Toronto in 1927 by boat from either Hamburg, Germany or Marseilles, France. Where would he have landed? How would he get to Toronto?

From Anonymous -- Assuming that he entered Canada through a Canadian port, it would have been Halifax during the winter months, or Quebec City during the rest of the year. Passengers rarely stayed on the boat beyond Quebec City - it was far faster to go the rest of the way by train. If you can find the passenger list, the railway would likely be identified, as tickets were to the final destination. If he was not from the UK, his port of entry might be shown on his citizenship record, if it still survives. (Some still do, while for others only an index card remains. You can request a copy of the file through Access to Information from Citizenship and Immigration). As well, if he ever entered the US through the Niagara Region at any point up until the late 1940s, there may be clues on the US Border Crossing records, which you can access through Ancestry.ca.
