It seems to me that your lawyer launched an EOI in Manitoba province. 1st of all launching EOI in any province does not cost a penny and after ITA the application fee is between 300 to 500 dollar in any province.
Now, launching an EOI does not mean that you have applied there. It just mean you have an interest in that province. If you have a good score they will send you ITA and then comes the part of application submission.
If you are talking about Manitoba, I will say It's very tough to get ITA there without any relatives living in Manitoba. But if you have close blood relative in Manitoba, your son may get an ITA. However, his score does say that you do not have relatives in that province.
