Hi Saras,
Since you are on Vancouver Island,(as pretty much everywhere)(I'm not sure whee you are) there are some different code requirements for each municipal district because of the different salt air stuff going on around the West Coast of BC. They vary wildely, as I found out about 30 years ago.
I'd suggest, as a start with the CEC and then get the municipality to supply you with their own local changes to the codes. Some of the ones I found one time would not let AL anywhere near the atmosphere. - i.e. corrosion.
Your only solution is to check the CEC and their amendmnts for the municipality you are in.

There has been growing consistency from jurisdiction to jurisdiction in BC over the last 30 years. As far as cables go there is a big difference from Vancouver to the rest of BC in air return plenums. Vancouver requires FT-6 flame ratings for cbles in plenums. I think the rest of BC goes with the NBC as ammended for BC. or FT-4. I don't know where aluminum wire is prohibited and I'd be surprised to learn that BC Hydro does not use it for it's distribution. I know there are a lot of people that just use copper and some of that is due to a mis understanding of the issues surrounding the aluminum wiring for branch circuits from the 80's.
