Are you looking for genealogy information prior to your ancestors emigration, or after they settled in Canada?
Can you provide additional information on your ancestral families, such as: birth dates, date of marriage, where they were married, date of arrival in Canada, where they settled? Were your families of the Roman Catholic or Greek Catholic faith? Do you know if other family members emigrated at the same time (children, siblings, parents, etc.)?
I would also suggest that you expand your search request to a few other online genealogy forums, such as http://www.ukraine.com/forums/genealogy/
. There are a number of members on those forums who may be able to further assist you.
