Looks like he was travelling alone. It appears he was going to his son, a blacksmith, in Alberta.
Men often went ahead to set up a home before families joined them. Arrival dates can be a bit fluid in the census records. I have had a look for Margaret and the children arriving but haven't been able to spot them at the moment. Not all records are on line...depends on port of arrival and date. Also, probably not all records survive, either.
