Nanny Job in Newmarket, Ontario

Looking for a part time nanny starting March in the Newmarket area for 2 boys age 5 & 7 years old.
Right now I need after school from 2:30pm-6pm - 3 days/week (mon-wed). Then once school is out (end of June) it would be full days Mon-wed from 8am-6pm.
5 year old has some developmental/speach delays, so someone with experience would be beneficial.
We also have 2 very friendly older small dogs.
Would include some meal prep for the kids and very light cleaning.
Both will be on the bus but must have drivers license, as pick up from school may needed on occasion.
