I assume you're talking about Python tkinter: https://stackoverflow.com/questions/29211794/how-to-bind-a-click-event-to-a-canvas-in-tkinter – Mike67 Sep 26 '20 at 20:24

You can have a look here: http://effbot.org/tkinterbook/tkinter-events-and-bindings.htm for an introduction on events binding.
A canvas is a widget so you can bind mouse events to it like:
def on_left_button_clicked(event):
# retrieve mouse properties eg coordinates from the event
c = tk.Canvas(root,....)
c.grid(...) # or pack
c.bind("<Button-1>", on_left_button_clicked)
Contrary to other widgets, the canvas provides helper function to related mouse coordinates to canvas ones (because the canvas can be "dragged"). See here for canvas specificities: http://www.effbot.org/tkinterbook/canvas.htm
