As your Canvas doesn't seem to have fixed width and height, I would include it into a Viewbox:

<ItemsControl.ItemsPanel>

            <Canvas x:Name="canvas" Background="DarkSeaGreen">
                <Canvas.LayoutTransform>
                <ScaleTransform ScaleY="-1" />
                </Canvas.LayoutTransform>
            </Canvas>
        </Viewbox>
    </ItemsPanelTemplate>
</ItemsControl.ItemsPanel>

Alternatively, place your entire UserControl into a ViewBox.
