Rather than applying at any lab with openings, consider what area of research you are interested in, what labs you are specifically interested in, and reach out personally to the professors/directors of the lab. Demonstrating a keen interest in a subject matter is important when it comes to considering what lab to volunteer in.  

Many people, with and without an Honours thesis and/or field experience take a gap year.  If you are considering applying to a clinical program, they look at an applicant’s research experience, grades, and teaching experience.  As such, taking a gap year to help build up your Cv in any of these areas is always a good idea - the more experience you have and can speak to, the stronger candidate you will be when applying for graduate training.
