I dont know about in canada but herein america treatment providers transfer/refer their clients on to longer term treatment providers for many reasons...

examples....
when they feel they are not qualified to work with the problems that the client has

when the client begins to show more problems then what they came in to treatment for ...this can signal to a treatment provider things like the client willfully creating more problems to please the therapist rather than work on problems or it can tell a therapist that the client isnt comfortable with that treatment provider so in order to help the client the treatment provider must stop being their therapist and send them to someone else who the client may be able to be comfortable/less triggered with.

some mental disorders here in america also require long term and sometimes inpatient treatment example people with dissociative disorders are usually in treatment for over 10 years and end up in mental wards on and off because of violent behaviors.

trauma therapy (opening up about past trauma) brings with it, its own unique and sometimes dangerous behavior patterns that require a long term treatment provider and inpatient treatment.

my suggestion dont worry so much on the fact that this treatment provider is transferring you to someone else after so little time. count your self lucky. unlike many others who spend years with the same treatment provider it will be relatively easy for you to transfer to another treatment provider....less paperwork and less emotional guilt over possibly wasting years on the same treatment provider only to not get helped. now you can get the help you need from this new treatment provider you will be transferring to with out having to worry about finding someone new after the short term treatment is over. long term treatment providers can take their time with you and help you to work on your problems one step at a time at a pace that wont cause you more harm or more problems.
