var notifications = Windows.UI.Notifications;

yourToastNotification.addEventListener("dismissed", function (e) {
    switch (e.reason) {
        case notifications.ToastDismissalReason.applicationHidden:
            // The application hid the toast using ToastNotifier.hide.
            break;
        case notifications.ToastDismissalReason.userCanceled:
            // The user dismissed the toast.
            break;
        case notifications.ToastDismissalReason.timedOut:
            // The toast has expired.
            break;
    }
}
