Law / Canadian born looking for help obtaining a Polish Passport [7]

Hi,
Both my parents were born in Poland and came here to Canada in 1970. Part of their immigration to Vancouver, Canada they had to give up all rights and citizenship of Poland. I was born in 1975 and trying to obtain my Polish passport. Does anyone know how I can go about doing this. My grand parents have passed away and my parents don't have any records of their heritage.
