When and where to wear my military uniform?

I recently transferred from Winnipeg to Montreal (Canada), and since I am new private I have a few questions about my uniform.

1) I have a meeting at the orderly room with my new unit today and I don't know if I should go on civilian or military dress. Which should I choose?

2) My only means of transport from campus to the barracks is foot (it's a short jaunt of 3km). Can i wear military dress during my walk?

Thanks!
