Assigning dynamically to a canvas a camera

Since I use stereo vision the 2 cameras are generated at runtime by a script, how would it be possible to dynamically assign to a canvas its camera in C# ?

I have tried that :

Canvas oLeftCanvas = ( Canvas ) m_oCanvas.GetComponent( "LeftCanvas" );
oLeftCanvas.camera = GameObject.Find( "leftCam" );

but Canvas.camera is protected and so I can't dynamically assign it a new value.

 

assign it to oLeftCanvas.worldCamera
