Hi John!
I have had a look at James' profile and added some notes to the bottom.
There are a number of options for records for him in Ontario, Canada. Unfortunately, I am unable to narrow them down at this time.
I would suggest to you that you might try working your tree forward at this time. If you are able to create profiles for the children of James and Catherine and source their birth, marriage, and death records, we may be able to narrow down where James was born.
Also I think you have Catherine duplicated, so her two profiles should be merged.
Let us know if you need any help with that!!
