If it's just "today's date" you need, just import datetime or mxDateTime 
or whatever, and call the functions in onPage.

If you have a specific string you need to pass, remember that a canvas 
is just a Python object.  You can add your own attributes.

class myReport:
    def __init__(self):
        self.canvas = canvas.Canvas( ... )
        self.canvas.myExtraData = { 'today': "Today is the Day" }

...
def onPageEnd(canvas, doc):
    ...
    canvas.drawString( x, y, canvas.myExtraData['today'] )
