He was entering the US from Canada on his way to a friend, Dan McGregor, at 16 Hayden Street, Toronto. He entered the US at Pembina, North Dakota. It's shorter to travel through the US than through Canada, which is why he was likely crossing the border. Indicates he had originally arrived in Canada at St. John aboard the Cassandra in March 1911.
1911 Canadian Census has him living in Marquette, Manitoba, working as a servant in the home of George Rankin. Says he immigrated in 1911. Also in the household is another servant who also came from Scotland in 1911 named Angus Comrie.
I found Angus aboard the Cassandra in March 1911 (altho' his first and last names are reversed on the passenger record). Interestingly, I do find Charles (last name looks like Cork) on the same ship. Both are bound for Winnipeg, but Charles says he was in Canada before from 1898 to 1910.
