Same here. In Newmarket, daycare centres are higher (about $10 higher than me), with only subsidy offering lower rates. Although....my sister is looking into daycare for my nephew as he has to leave my care by March to make way for baby sister. His age bracket (3+) does appear to be a bit less than me. I'm a flat rate across the board. I think, as Bright Sparks said, most (in my experience) who want large centres do so because of reliability and, sadly as of late, the license.
I guess it all depends on the area you live in too, with high turn over. In my old location, which was rural, I kept clients for up to 7-8 years. Honestly, they all became close friends and options were limited. Once all my friends stopped having kids and the younger families started moving in, I started getting pushed out by 2 new daycares in the centre of the village that were more convenient.....and by the woman in the neighbouring village who charged a pittance but brought in 15 kids. In my new place, I have no problems, even with high competition. But that may be this area. I know people are struggling all over. Hope you fill up soon
