There are a number of ways to obtain citizenship or dual citizenship, such as birth, naturalization, marriage or your parents or grandparent's citizenship
It is quite possible that you qualify for US citizenship based upon your grandmother having been born in the US
Because these situations are assessed on a case by case basis and depend upon an number of circumstances and criteria, one must inquire with the relevant government officials, in this case, in the US and begin an inquiry and application
You may begin your quest by contacting the US Embassy or Consulate and they will be able to assist you in making your application and can guide you through the process, telling you what you need to have or do
Here is a Canadian government link detailing information on dual citizenship.
but ultimately, you'll need to contact a US Embassy or Consulate and you can find out how by calling the Department of Foreign Affairs and International Trade at 1-800-267-8376
They'll help you get in touch with the proper US resources.
I wish you the best of luck with this.
