I want to create some text in a canvas:
myText = self.canvas.create_text(5, 5, anchor=NW, text="TEST")
Now how do I find the width and height of myText?

A Frame is designed to be a parent container of other widgets. A Canvas is like a canvas that you can draw somethings on it like lines, circles, text, etc. A Canvas can be used as a parent container as well but it is not designed for that at the first place.
The Canvas widget supplies graphics facilities for Tkinter. Among these graphical objects are lines, circles, images, and even other widgets. With this widget it's possible to draw graphs and plots, create graphics editors, and implement various kinds of custom widgets.
A tkinter canvas can be used to draw in a window. Use this widget to draw graphs or plots. You can even use it to create graphical editors. You can draw several widgets in the canvas: arc bitmap, images, lines, rectangles, text, pieslices, ovals, polygons, ovals, polygons, and rectangles.
bounds = self.canvas.bbox(myText) # returns a tuple like (x1, y1, x2, y2)
width = bounds[2] - bounds[0]
height = bounds[3] - bounds[1]
See the TkInter reference.

This method seemed to work well if all you are interested in is the width and height of the canvas being considered, using the bounds of the box and then checking the differential works just as well if you want to do it that way.
width = myText.winfo_width()
height = myText.winfo_height()
