Is this an accredited Montessori school?

No accreditation or membership from a recognized Montessori body (AMI, AMS, or Montessori Canada) is on file for this listing. Because "Montessori" isn't a protected trademark in the US or Canada (a 1967 US trademark ruling put the term in the public domain in the US), any school can use the name regardless of how closely it follows the method. That doesn't mean this school isn't authentically Montessori; it means accreditation status isn't the way to check here. Ask the school directly about their teacher training (look for AMI or AMS-trained staff) and ask to observe a classroom work cycle.

Accreditation is not the same as an operating licence. A provincial/state child care licence or private school registration only confirms a school is legally allowed to operate — it says nothing about whether the teaching method is Montessori.

Teacher credentials matter too. Ask how many lead teachers hold AMI, AMS, or MACTE-accredited teacher training — a strong signal independent of the school's own accreditation status.
