I'm on refugee claimant.
My husband couldn't reach here due to unconditional situation.
How can he join me.my lawyer doing nothing not even guiding me
It looks like you are still waiting for your refugee hearing.
If that is the case, then there is really no way for your husband to come to Canada right now. He can try applying for a TRV, however it will most likely be refused. If he manages to get a TRV approved, then he can try traveling to Canada once the COVID-19 travel bans have been lifted.
If he cannot get a TRV approved, then you will have to wait until you have been accepted as a refugee / protected person and your PR application has already been processed (you will include him in your PR application). This will still take a few years from now.
