ISO Preschool in Waterloo area

Hi,

My family is potentially moving to Waterloo this fall. ATM my child (currently 2.5yo) is enrolled in preschool here in BC. Here, preschool is 2 hours a day, 3ish days a week.

Im having trouble finding something similar in Waterloo. I'm not looking for daycare, but a true preschool program. I'd like for it to be somewhat educational (our current preschool is Montessori/reggio-emilia), but the Montessori schools I've seen are crazy expensive in Waterloo! Right now I only pay $300/month for my child. Any recommendations for high-quality preschool programs in the area?
