Hi, thanks for your question.
In the situation you have described I do not think there is any risk of you being infected with HIV.
If you were tested in Canada we have very good procedures and protocols in place to prevent re-use of medical equipment, and I can confirm that most needles used these days have safety locks that prevent the needle from being re-used.
Please leave a comment to let us know if this answers your question or if you need more information.
