I suggest you find census records that may help with the birthplaces. Sometimes they are specific. Try 1851, 1861, and 1871 for the wife.
For deaths you will need the church records in Quebec. These can be found at ancestry.com or are browseable on familysearch.org.
I'd suggest you have the film church record film sent to your local Family History Center. You'll find loads of info on you extended family!
