From the bill:

110 (1) ‘Fetus’ means a person at any point of development from and including the moment
111 of conception through the moment of birth. Such term includes all medical or popular
112 designations of an unborn child from the moment of conception such as conceptus,
113 zygote, embryo, homunculus, and similar terms.

It’s not the only place they use or redefine words to mean what they want them to mean.
