After searching for a good lawyer, I came to some conclusions which may help some other people and also they help me:
To my surprise, the creator of this forum Cambell Cohen does NOT help with citizenship cases which are already in process (which face RQ or citizenship judge hearings). The sighted liability issues?!!?!
As it seems, it is not easy to find a lawyer with an affordable price for citizenship cases:
After contacting a very reputable company B. in Toronto, they gave me a price close to $7,000 to review the case and another $7,000 in case to go to court (close to 14K total). When I tried to negotiate the price, they told me to go somewhere else!!!!!!
There are many federal court cases who have won against federal judges (and many who have lost) in the federal court registry website from whom I had never heard before. Bottom line is that they go by the word of mouth.
There is a website called bestlawyers (google search it) which introduces some names but a full search requires a subscription of $200 to show the full list.
I am still searching in Montreal and appreciate anyone with a positive experience.
