Yes. The tenant should be considered the landlord of the sub-tenant. Therefore, he can evict, just like any landlord.
no
It depends. If the sub-tenant was there by right and the landlord allowed a sub-lease, then that's a situation where nothing has gone wrong. If the landlord is suing, it sounds instead like the tenant did not have the right to sublet and in that case they are responsible to complete the lease and the sub-tenant may not have had the right to be there.
No lease does not mean no rules. If a tenant causes excessive damages you can still sue them.

Yes, it is possible to sue for emotional distress in Canada. However, the claimant must prove that the emotional distress was severe and that it was directly caused by the defendant's actions. It is recommended to consult with a legal professional to understand the specific requirements and processes for such a lawsuit in Canada.
A sub-lessee is called a sub-tenant.
The landlord could sue the decedent's estate.
You can sue them in court.
If the person has the legal right to live there on a month-to-month basis, he is a tenant. But we are presuming that you, the landlord, didn't rent the unit out to this person: perhaps your tenant did, known as subleasing. If you, the landlord, allowed this, then you have to have your tenant evict the sub-tenant. If you didn't allow this, then you have to enforce the terms of the lease, and make your tenant correct this problem immediately or you can evict him, which automatically forces the sub-tenant out.
If you sub-lease a unit, then the tenant that leases to you is considered your Landlord. Their landlord is NOT the sub-lessee's landlord. The master landlord, who usually does not allow subleasing, is not bound by the Landlord/Tenant Act toward the sub-lessee. So if they kick out your sub-landlord, they are kicking out EVERYONE. The master landlord cannot lock out his tenant unless they legally evict that tenant. Since a sub-lessee doesn't have the same rights, then they too are locked out.
I can't answer definitely without more information. Basically, if the tenant did something wrong, then the landlord may very well be in a position to sue to be compensated for this wrong.
You cannot sue for back rent to a tenant who has sublet in the apartment, when you the landlord did not give permission for that to happen in the first place. You have the right to evict the tenant or to force the tenant not to sublet the apartment. You could write into the lease that if you tenant does sublet, a fee can be charged for every month the subletting occurs, until the subletting ends.
No, but the tenant can report such a code violation to the municipal or county Code Enforcement Bureau.
