The link CarolA3 points to is actually a thread I started.
CdnGran and myself actually came into contact via Ancerstry.com . Her Great-Great Grandmother (Adelaide Clough Pinder Ridsale) is actually my Great-Great Grandfather's daughter (Stephen Pinder - B1803 - Kilham). We may be related even earlier than that via marriage of Stephen Bennison (1739-1813) to Mary Pinder (1760-1844), but I have no firm documentation proving that this Mary is related to my branch (Love to find out though).
Back to the matter at hand regarding Adelaide. I am pretty sure she did not leave with the whole Pinder clan to Canada. I am fortunate in that I do have some letters handed down over the years, which suggest that Adelaide was elsewhere than with her parents (Stephen Pinder and Mary Ann Coulson).
A letter dated 1853 from Stephen Coulson (Mary Ann Coulson's father) to Mary Ann Coulson, living in Upper Canada at the time states: "Sister Harriot has been only poorly but has gotten better. Sister Selina his very well but George his only very poorly There is a great many ?? inquires after your house you get on we had a letter from Adlaide and was very glad to here they were both well and was doing well. I sent them a newspaper and will write to them next week."
(Be warned, it's a difficult read)

"When you write again will you tell us where all my cousins are and what they are doing and how Mary gets on with her store and how many children cousin Adelaide has and how many cousin M?
has. You sent us a new York ledger and a newspaper. "
https://1drv.ms/i/s!AifC60WL0cSMuU_8lWM39_5xxxEiThe 1851 UK census put here with the entire Pinder family in Bridlington/SKipsea.
The 1853 suggests she is no longer in the UK.
The 1853 and 1860 letters suggest they are not with their parents
The question is did they go straight to Canada or did they come via the US.
The other question that avm228 alludes to is a bit of a mystery and one I would love to find an answer to: There are two transcripts from the Yorkshire, Archbishop of York Marriage licences index (via Findmypast). One indicates a marriage licence of Stephen Pinder to Mary Ann Coulson (License date Apr. 12th, 1835, record sequence number 37, page 266) the other to a Mary Ann Clough (License date Apr. 6th, 1835, record sequence number 36, page 266)
An old fashioned admin error..? I suspect not, but what might of happened here?
