North Vancouver have same rule with no secondary suite if you have daycare.

Can I install a secondary suite?
You can install a new secondary suite in your single family home, unless:

you do not live in the house
you plan to build it in an accessory building or parking structure
there is already an existing suite in your home (a maximum of 1 suite is allowed)
you have boarders or lodgers
you have a home occupation (home-based business), such as an office or daycare
you want it to be larger than 90m2 (968 sq ft) or 40% of your residential floor space
