Census help needed in Canada

I am trying to help someone find out information on a Ingeborg Berliot Kristiansdtr. born 3-14-1886 in Enebakk, Akerhus, Norway. I found her birth and baptism in the scanned parish register 1867-1888 Enebakk. Ingeborg's parents were Kristian Albert Johannessen, born 1860 and Laura Larsdtr. born 1860. I have found the information on her in Norway. The person looking for information on Ingeborg knows the following: Ingeborg immigrated in 1912 and wrote a letter to her brother in Norway that stated she was married to a Anderson and had two sons, ages fourteen and fifteen. The letter was dated 1930. She was living in Cornwall, Ontario, Canada. The person would like to know what Mr. Anderson's name was and the sons names. She is planning on visiting the area in Canada and would like to reconnect with relatives of these people. I have searched various ways and know that Cornwall is in Stormont County. I have Ancestry for the states, but not Canada. I have tried everything I can think of to help her, but with no luck. I tried finding if she was married in Norway, but could not find a marriage in Enebakk records, or a list of her leaving. Any help would be greatly appreciated. Thank you for any help. I know this one is a long shot! Kathy
