Nanny Job in Brampton, Ontario

Looking for a nanny/caregiver for two children. My daughter is 8 years old and is in full time education with many activities outside of school including horse riding, swimming, art, gymnastics and ninja training. My son has just turned 1 years old and is currently at home full time. My wife and I are both in high paced jobs and while I work from home my job requires me to be available on the phone at all times and requires spur of the moment travel abroad which is disruptive to children's routines (something I am a huge advocate off). We are looking for a nanny/caregiver to supervise, engage and mentor the children. Weekend supervision is required once every two weeks if at all possible. Looking for a Nanny who can work up to 40 hours per week in total.
