delivered the opinion of the Court.
These three libels in admiralty in personam were brought in the federal court for western New York, by owners of cargo laden on the steamer “ Yorkton ” to recover for loss resulting from the sinking of that vessel in a collision with respondent’s steamer “ Mantadoc,” in Lake Superior, on the American side of the international boundary line. The respondent moved, in. each case, that the District. Court exercise its discretion to decline jurisdiction and dismiss the libels on the ground that all the parties were citizens of Canada and that the controversy concerned “ matters . . . properly the subjects of hearing and determination” by the. Canadian courts. The motions were granted, 49 F. (2d) 802, 804; and the decrees of the District Court were affirmed by the Circuit Court of Appeals for the Second Circuit, 51 F. (2d) 1007. This Court granted certiorari.
Shortly after the collision, the Wreck Commissioner of Canada held a formal investigation, as required by law, respecting the circumstances of the collision, and determined that the masters of both vessels were at fault. The respondent then instituted in the admiralty court of Canada a proceeding for the judicial determination of the liability as between the colliding vessels and their owners.
*418
The libellants’ motive for invoking the jurisdiction of a court of the United States, instead of that of the Canadian court in which that proceeding was pending, appears in affidavits filed with the exceptions to the libel. Under the Canadian law, it is stated, if both colliding vessels .were at fault each vessel would be liable for not more than half of the loss; and the salvaged value of the York-ton might not suffice to pay its share. % See
The Milan,
Lush. Adm. 401. Under our law the innocent cargo-owner can recover full damages from the non-carrying vessel.
The New York,
The libellants concede, as they must, that in a suit in admiralty between foreigners it is ordinarily within the discretion of the District Court to refuse to retain jurisdiction; and that the exercise of its discretion will not be disturbed, unless abused.

Unione Austriaca di Navigazione,
First.
The contention that the jurisdiction was obligatory rests upon the fact that the collision occurred within the territorial waters of the United States. The argument is that a cause of action arising from a collision occurring on territorial waters of the United States arises out of its laws, since within its territory there can be no other law,
Smith
v.
Condry,
The- respondent insists that the doctrine of
lex loci delicti
has no application to cases of collision on the Great-Lakes; that the Great Lakes and their connecting channels constitute public navigable waters, irrespective of the location of the international boundary, and possess all the characteristics of the high seas,
The
Eagle,
We have no occasion to enquire by what law the rights of the parties are governed, as we are of the opinion that, under any view of that question, it lay within the discretion of the District Court to decline.vto assume jurisdiction
*420
over the controversy. The suggestion drawn from the language in
The Belgenlcmd, supra,
that such discretion exists only “ in cases arising beyond the territorial jurisdiction of the country to which the courts belong,” is without support in either the earlier or the later decisions of this Court. Nor is it justified by the language relied on, when that language is read in its context. The case of
The Belgenland
arose out of a collision on the high seas between foreign vessels of different nationalities; and the objection was raised that‘the courts of the United States were wholly-without jurisdiction. Mr. Justice Bradley, speaking for the Court,. replied that jurisdiction in admiralty did exist over, controversies between foreigners arising without the territorial waters of this country, but that the court in such a case would use its discretion in determining whether to exercise it. That the Court had no intention of denying the existence of similar discretion, where the cause of action arose withjn the territorial waters of this country, is shown by its reference to the cases of
The Maggie Hammond,
*421
The rule recognizing an unqualified discretion to decline jurisdiction in suits in admiralty between foreigners appears to be supported by an unbroken line of decisions in the lower federal courts.

The question has most frequently been presented in suits by foreign seamen against masters or owners of foreign vessels, relating to claims for wages and like differences,

or to claims of personal injury.

Although such cases are ordinarily decided ac
*422
cording to the foreign law, they often concern causes of action arising within the territorial jurisdiction of the United States, compare
Patterson
v.
The Eudora,
Obviously, the proposition that a court having jurisdiction must exercise it, is not universally true; else the admiralty court could never decline jurisdiction on the ground that the litigation is beween foreigners. Nor is it true of courts administering other systems of our law.
*423
Courts of equity and of law also ocassionally decline, in the interest of justice, to exercise jurisdiction, where the suit is between aliens or non-residents or where for kindred reasons the litigation can more appropriately be conducted in a foreign tribunal.

The decisions relied upon by libellants are inapposite for several reasons. They were not in admiralty causes; nor did they involve alien or non-resident parties. Compare
Second Employers’ Inability Cases,
Second. There is no basis for the contention that the District Court abused its discretion. All the parties were not only foreigners, but were citizens of Canada. Both the colliding vessels were registered under the laws of Canada; and each was owned by a Canadian corporation. The officers and the crew of each vessel — the material witnesses — were citizens and residents of that country;' and so would not be available for compulsory attendance in the District Court. The cargo, in each case, was shipped under a Canadian bill of lading from one Canadian port to another. The. collision occurred at a point where the inland waters narrowed to a neck and the District Court concluded that the colliding vessels proceeded *424 in United States waters unintentionally. If the libellants are entitled to have applied the law of the United States in respect to the liability, the Canadian courts will, it must be assumed, give effect to it. The District Court embodied in the decrees an order that the respondent should appear and file security .in any action which, might be instituted by the petitioners in the admiralty courts of Canada, so that petitioners would not by dismissal of the libels lose the security gained by the foreign attachment. It is difficult to conceive of a state of facts more clearly justifying the refusal of a District Court to retain jurisdiction in a cause between foreigners.
