Narrative:

Cleared by apron control to taxi from gate to runway 10 via taxiway G. At taxiway G, ramp control told us to contact ground. We were already holding short of runway 10 at the time we contacted ground. Ground control told us to taxi to runway 10 and contact tower when ready for departure. The first officer and I understood this as back taxi on runway 10 and contact tower. We taxied onto runway 10 and called tower. He informed us that next time we need clearance to taxi onto the runway. The first officer and I both acknowledged the tower controller. Our perception was that we were cleared onto the runway. In hindsight, I should have questioned the ground controller for clarification due to the phraseology of the taxi instructions. This was only the second flight together as a crew and the first trip into montreal for either of us.
