Originally, the game farm was home to orphaned and injured indigenous species like owls, bears, and deer.

[1] The city of Moncton took over the park in 1979 and began acquiring more exotic species which served as a catalyst for the renaming the farm to Magnetic Hill Zoo.

At the same time, the zoo also expanded by adding the Primate Conservation Centre, frog bog, the koi pond, bird garden, the Camel-Zebra exhibit, and a children's playground.

A new food concession stand was also renovated in 2005 and the zoo was awarded the New-Brunswick Top Attraction Status.

[1] In 2006, significant upgrades were made to the walking path system and signage in order to make the zoo more accessible to the public.

The zoo's animal collection was expanded to include mandrills, colobus monkeys, and two African lion cubs.

[7] Magnetic Hill Zoo has more than 400 animals, including over 70 domestic and exotic species of birds, mammals, insects, reptiles and fish.
