I will be attending a conference at Carleton University. I will have my then almost 15-month old son with me who has never been separated from me/dad. I am looking for someone who can help me through the day with him on my side.
I would suggest contacting the job centre at the university. It's been years since I went there, so I don't have the contact information anymore, but I'm sure that the main switchboard could direct you. As a student, I found several jobs that way. No matter what you do you'll end up with a stranger, but if your ad. is specific and you get references, you should have good luck.
