Hi anonymous.
It would help others to help you if you could link to the profiles of the people you're asking about or provide some more information on them with regard to your question, e.g. a rough idea of the time they may have left Scotland, etc
If you're looking for information on them leaving Scotland to go to Canada, then I would suggest a search of the passenger & shipping lists at the National Archives of Scotland & the URL for that is

All the best
