“there is no limit on how much it can be raised unless its obviously punitive. Eg 100 a month raise is acceptable, 1000 a month is obviously punitive and likely to be disallowed by our Residential Tenancy Dispute Resolution Service”

So there is a limit, but it depends on how well the landlord gets along with the people making the decision, instead of being codified into law.

Here, a LL can evict a tenant who refuses to pay in less than a month. None of this 6 month wait baloney and then two postponements as the tenant games the system and continues to destroy the property. In AB if there is proof of wilful vandalism the eviction period is 24 hours.

This is better than some scenarios, but again seems ripe for abuse.
