This is why I posted a while back that the cost varies wildly and it is hard to come up with a ballpark figure bro.
You could save a lot on cost by sourcing materials and going to the subcontractors directly yourself. Roof guys, glass guys, tile and fixture setters, cabinet guys etc instead of having one contractor subcontract them to others. Buying your own lighting fixtures, doors, door knobs etc could also save you a bundle.
Some provinces will also have access to cheaper materials. Up north sand and CHB are cheap because of close proximity to the quarry. And sometimes access to tax free cement and rebar
Location and terrain also play a part. A site with wide, accessible open working areas will be cheaper vs one that is already boxed in by other atructures. If the site needs clearing or leveling that will also add to the cost.
Quality of finishing materials used will also affect cost. Frameless vs framed glass. Ceramic tile vs granite. Solid wood vs laminates. Solid wood doors vs panel ones. List goes on and on.
