How this list is ranked
Centres are ordered by a rating estimate. That is not the raw Google star average: the estimate blends a centre's own average with the average across Ottawa, and it weights the two by how many reviews the centre has.
The city average used here is 4.3 stars. It is taken across the 8 Montessori daycares in Ottawa that clear the review bar.
A centre with 10 reviews sits exactly half way between its own average and the city average. Past that it leans on its own record. Below it, it leans on the city.
A centre with fewer than 5 Google reviews is never ranked on this page. It can still be a good centre; there is simply not enough evidence to place it against the others, and placing it anyway would be guesswork with a number attached to it.
Google ratings are third party. They are shown as plain text, they are not collected by MapleCub, and they are not marked up as review data anywhere on this page.
The badges below each centre report facts about the listing: whether the provider has claimed it, whether opening hours are published, whether a provincial registry reported an opening, whether the centre is enrolled in CWELCC. None of them change the score. None of them change the order.

Questions about this list
How many Montessori daycares are there in Ottawa?
MapleCub lists 21 Montessori daycares in Ottawa. 8 of them have at least 5 Google reviews, which is the bar to be ranked on this page. The top 8 are shown here.
How is this ranking worked out?
Centres are ordered by a rating estimate. That is not the raw Google star average: the estimate blends a centre's own average with the average across Ottawa, and it weights the two by how many reviews the centre has. The city average used here is 4.3 stars. It is taken across the 8 Montessori daycares in Ottawa that clear the review bar. A centre with 10 reviews sits exactly half way between its own average and the city average. Past that it leans on its own record. Below it, it leans on the city. A centre with fewer than 5 Google reviews is never ranked on this page. It can still be a good centre; there is simply not enough evidence to place it against the others, and placing it anyway would be guesswork with a number attached to it.
What counts as a Montessori centre here?
A centre counts as Montessori here when the word Montessori appears in its own registered name. That is a name test, not an accreditation check. MapleCub does not verify membership of CCMA, AMI or AMS, so a centre on this list may or may not hold one.
Are these MapleCub's own ratings?
No. The star ratings and review counts on this page come from Google, they are shown as plain text, and MapleCub does not collect them, does not adjust them, and does not mark them up as structured review data anywhere on the page. What MapleCub adds is the ordering. The method above says exactly how that is worked out.
How do I check that a centre on this list is licensed?
Every centre on this list is a licensed programme in MapleCub's records, each listing page shows the licence status MapleCub holds for it, and the authoritative record behind both of those is the province's own registry. Look the centre up there by name before you enrol. Confirm the licence is current.
What about the other daycares in Ottawa?
224 licensed child care programmes in Ottawa have a listing on MapleCub, across every programme type. The city page lists all of them. Filters there cover age group, subsidy and hours.
