I think you can create toolbar for every canvas and show/hide them when tabs.currentTab changed:

class MultiTabNavTool(qt.QWidget):

    def __init__(self, canvases, tabs, parent=None):
        qt.QWidget.__init__(self, parent)
        self.canvases = canvases
        self.tabs = tabs
        self.toolbars = [NavigationToolbar(canvas, parent) for canvas in self.canvases]
        vbox = qt.QVBoxLayout()
        for toolbar in self.toolbars:
            vbox.addWidget(toolbar)
        self.setLayout(vbox)
        self.switch_toolbar()
        self.tabs.currentChanged.connect(self.switch_toolbar)

    def switch_toolbar(self):
        for toolbar in self.toolbars:
            toolbar.setVisible(False)
        self.toolbars[self.tabs.currentIndex()].setVisible(True)
