Is rennet in cheese listed under another name on the ingredient label of cheese?

I'm a vegetarian, so I don't eat rennet. I don't know if it's different where I live (in Canada), but most cheese do contain rennet, from what I've heard. I've never actually read this ingredient on the label of cheese though. Is "microbial enzymes", "enzymes", "bacterial enzymes", "bacterial culture", or something else, a synonym for rennet?
