I am researching my family in the UK and have found two ancestors apparently born in London, Canada West. They are :-ASK OLIVE TREE Answer: Dear John, Canada West became Ontario but Ontario did not begin civil registration until 1860 [sorry this is a typo, the year was 1869!]. That means you must search church records for your ancestors' baptism.
Hannah Olivant born about between 1854 and 1857 and John Olivant born between 1856 and 1858. (From UK census information). Parents Isaac Olivant and Ann Olivant.
Is it possible that their baptism records have survived and if so could you advise me on the best place to look for them?
The next problem however is to determine IF the necessary church records exist! Your first step is to note your ancestors' religion, then find the relevant churches for London Ontario that have surviving records.
Next you need to know what District London was in for the years you need. Canada West was divided into 20 Districts and within those Districts were various counties. See the linked teext for Canada West to determine the district and county name that you need.
Having armed yourself with the needed facts (religon, district and county name) you can have a look to see what church records exist between the years 1854 and 1858
You might check the Ontario Archives and London Public Library for help with finding available Church Records
You should also have a look at the Ancestor Birth Record Finder for ideas on other places to search.
