Daniel Bourne is a U.S. citizen who lives in Fargo, North Dakota. For many years, he has had a cottage on Manitoba's Lake Winnipeg. In recent years, however, he has made little use of this property and, given this, he has sold the property. While there was a gain of $50,000 on the sale, Daniel assumes that he will not pay Canadian taxes on this amount as he is a U.S. citizen. Is he correct? Explain your conclusion.
