Nanny Job in Montreal, Quebec

We are two hard working parents of two lovely girls. One is 12 the other one 5. We are looking for help with housekeeping, laundry, help with the kids and sometimes help with meal preparation. We are looking for somebody we can build a long term working relationship with, someone autonomous, thorough, organized and punctual. We live downtown close to a metro station. We need someone 2 days per week (Mondays and Thursdays was working well for us, but could be any day as long as it's spaced out that way). We don't have pets.
