Do you know any good lawyer in Greater Toronto Area?

Thanks
Unfortunately not, but again, go www.lawyer.com put the location, it will give you options, and starting from there Google them, read reviews. You'll find someone good for sure.
And one very important thing: stay away from immigration consultants. Sometimes they advertise themselves as lawyers, and do some H&C but trust me they don't have enough knowledge and experience.
 
She is by herself back home and my father passed away couple of months ago. PGP is hit and miss, not easy to get name picked in PGP

As already specified your mother would need to be in Canada to apply for H&C and you will be responsible for paying for her dialysis out of pocket during her H&C application. That will be around 70k/yr and you would need to find a dialysis unit with space to accommodate a visitor. You would need to prove why she can not live in her home country and why she should be accepted when her medical costs exceeds the medical admissibility level. This is going to be more challenging than you may think. PR is not guaranteed. Does she have any family members in her home country?
