Nanny Job in St. Catharines, Ontario

We are expecting our 3rd child in the winter, and are looking to hire a reliable, patient, calm, mature, loving individual to help us care for our new baby when I return to work in June 2021. We will also need care for our 2 older children, ages 5 and 8, some evenings, over the summer months, and occasionally during the school year if they are at home for the day.
We have a very friendly family dog, who will also be home during the day. She naps for most of the afternoon, but will need a bit of love and attention (and to be let outside to play in the backyard), over the course of the day.
We live in Port Dalhousie, and have a big backyard for the kids (and dog) to play in. We will need help from 8am-4/5pm Mon-Friday, with occasional opportunities to babysit on weekends/evenings (1-2x/month), for additional pay, although this is not required or expected. We use a meal delivery service, but occasionally need help prepping for dinner before we get home (chopping veggies etc).
5yrs experience in child care, and experience with babies 3-12 months is required for consideration (candidates without this minimum experience will NOT be considered). Familiarity with the Montessori method is an asset, but not required.
