I would say for CCNA Level 1 to 3 you don't really need to go into class for it. Just study on your own and then do the exam. After that take the class from BCIT since they have the lab/equipment/hardware for hands on practice that you will need.
For Network+ A+ Security + just read a book and do the exam hell you can even download the study guide from
Free MCTS MCITP CCNA CISSP and Network+ practice exams, study notes and forums
I would use that site contains lot's of info you will find helpful.
