The CanadianNanny.ca app has a filter option for both families and nannies. When using the app, you will see a 'Filter' in the top left corner. Clicking on it will pop up the menu below:
For families: There will be filters such as location, travel distance, rate, experience, qualifications, and whether they have a completed background check or require sponsorship.
For nannies: There will be filters such as location, travel distance, rate, required experience, required qualifications, availability, and whether they are willing to assist with sponsorship.
