Daycarebear: This is an awesome search engine and it is FREE for everyone who uses it, lets you find homecare providers by postal code and then other special needs / request choices and lists in order of closest. Really saves parents time from contacting unsuitable locations about openings and it limits the provider to ONE active ad so it is less change of wasting time contacting the 'same provider' whose posted multiple ads with slightly different wordings and so forth.
London.kijiji : Again another local website that specials in online classifieds. It is of course FREE unless a poster chooses to 'bump or feature' their ad. However it can have many many ads to go through that are 'unsuitable' to your needs and therefore can be much harder to find as the 'search' by postal code feature is not always as accurate in the list it brings up and there are often 'multiple ads' from the same poster clogging up the feed on searchers.
GoDaycare: Another FREE option or everyone who uses it that can be searched by postal code.
Facebook: Facebook has a local to the London and surrounding area group that parents and providers can request to join in order to search for home based childcare.
