Shake And Take I Am Going To Take An Orientation Session Next Mon, Should I Shake Hands With Others Who I First Meet?

I am going to take an orientation session next Mon, should I shake hands with others who I first meet? - shake and take

I will be an orientation meeting held on Monday and will be my first day at work. (I'm in Canada.) So, I shake hands with others, the orientation during the first encounter? Should I introduce myself, but others do not wait for the introduction of another?

In fact, what about my first meeting with my colleagues? You have to shake hands?

Please help, thank you!
