Any lawyer license din any province in Canada can represent you in filing your immigration application. However, no lawyer will facilitate any job sear for any client. If any lawyer states so, that is completely fraud. The max the lawyer can do is to refer you to some job search agencies, the veracity of which is a client's responsibility.
As a lawyer, who has practices law in 3 countries, and also immigration law in US, a lawyer is way more qualified in handling an immigration application, as compared to a consultant, whose minimum qualification is a high school graduation. Also, lawyers will be able to assist and represent a client in courts, if need be, whereas consultants cannot.
So do your research well and get a lawyer, whom you are comfortable with.
