Hi Paul, special for you for your own researching interests, I thought I'd pop back in to tell you what sorts of info is on my own (Manitoba!!!) birth certificate and original birth registration forms. I pulled them out to have a look at mine. Don't know what other Provinces forms look like, but assume pretty much the same bits of info on them for births.

Birth Certificate: a wallet size card lists:

1) Full name, givens and surname.
2) Birth date
3) Birth place
4) Gender
5) Date issued (last date the newest one was issued to you)
6) Registration number (the file number with the vital stats folks)

Birth Registration Form (again, Manitoba for me):

Mine says "Official Notice of a Live Birth" and remember when reading it that this form is from my birth as standard form for Manitoba in 1954! but likely info pretty much the same these days?

1) Place/location of birth (including the name of hospital on mine )
2) Full name of child.
3) Gender.
4) Single/double or plural birth
5) Are the parents married to each other?
6) Date and actual time of birth.
7) Fathers name.
8) Residence of father.
9) Citizenship (of father)
10) Racial origin of father.
11) Age of father
12) Birthplace of father.
13) Occupation of father (a) trade, profession or kind of work / b) kind of industry or business
14) Full name of mother (plus includes names of former husband/s)
15) Residence of mother
16) Citizenship of mother
17) Racial origin of mother
18) Age of mother
19) Birthplace of mother
20) Occupation of mother a) trade, profession or kind of work / b) kind of industry or business (answer AT HOME if unemployed)
21) Children of this mother born alive/now living/stillborn
22) Weight at birth / length of pregnancy
23) Where were the parents married
24) When were the parents married
25) Name in full and residence of attending physician
26) Relationship of informant to child (who gave the bith info. Usually the mom)
27) Were you in the house at the time of birth?
28) Signature of mom or whoever informed, including their exact location of residence

In cases of unmarried parents, and the like, fathers name and information usually completely unfilled out as far as I know

It was great fun for me to find my birth length, birth weight and actual birth time on my registration ... and a shock to find "Scotch Halfbreed" for Mom's racial origin Those were the days, eh? Mom was English, Cree, Scotch, Fench and perhaps a wee bit 'o the Irish in 'er somewhere ("bastards" and "halfbreeds" not very socially acceptable in those days )

Maybe folks born in other Provinces can verify if their Province registration forms pretty much the same info collected ?

Hope this is helpful for you to know Paul!
