New England arriving in Halifax for the first time since 2006 by my records.
The ship appears to be loaded, so if it has cargo for Halifax, it must have received a special dispensation or very quickly transferred to Canadian registration.
I suspect that the ship's appearance here is related to Monday's fire at the Irving Oil refinery in Saint John, that disrupted normal production. Irving Oil spokespersons indicated that they had product in storage and other sources for fuel, so shortages are not anticipated.
If there is an extended shut down of all or part of the refinery, they will have to bring more refined products in from elsewhere, but that may take time. In the meantime they may be re-distributing stored product to meet demand.
