Try first removing the module('canvas') line (module() is not useful
in situations like this, where you are constructing your own object
and returning it at the end), and then setting the global variable
yourself at the end, e.g.:

-- Create base instance
local baseInstance = Canvas.newcanvas(otherModule:CreateSurface
{caps='DSCAPS_PRIMARY|DSCAPS_FLIPPING'})
_G.canvas = baseInstance
return baseInstance
