sponsor / social assistance

[Saluma]

Hey everyone,

I've a question:
I know as a sponsor you're not allowed to collect social assistance.
My boyfriend is going to sponsor me within the next few months through as common-law.
He has a 5 year old son who's living with us. The biological mother is not paying any child support whatsoever, so my question is:

1. Can my boyfriend collect child subsidy for his after school care and still sponsor me?

2. Would he be allowed to collect rental assistance/rental subsidy or does this disqualify him from being a sponsor?

I'm all in all just not sure what is considered social assistance...I know welfare is but other than that, I don't know...

Thanks for your help!
I appreciate it!
