Aqua therapy??

Hey friends, I’m here to ask for a suggestion, I hope you guys can help me better with this. My uncle has met with an accident a year ago. And he has been through several major surgeries to fix his spine fracture and other injuries. By God’s Grace, we could bring him back to our life.
Mentally he is perfect now, unfortunately physically he is still suffering. We don’t know whether it is the after-effects of the surgeries. For the past six months, he is suffering from this chronic back pain. He has been through an aqua therapy in Oakville, at the beginning it was effective and he could do his daily life works on his own and was fully satisfied. But when he stopped the therapy the same issues are arising again, he is literally desperate and depressed.
I really want to help him to overcome this, so please help me with this guys, should I recommend him to continue the same aqua therapy in Oakville or switch to any other treatments? If so, which treatment should I refer him? And it will be more helpful if you could suggest a clinic near Oakville. And if you or any of your friends personally know any medical rehabilitation treatment centres near Oakville or physiotherapy treatment in Toronto, please mention and reply. It would be a big help to me.

Have a nice day.
Thank you in advance.
