Faucet installation in Toronto usually means working around plumbing older than the last three owners of the house. In the semis and Victorians of Riverdale, Cabbagetown and The Junction, the supply stops under the sink are often original and will not turn, and the wall behind the escutcheon is plaster, not drywall. I plan for that before I start.
I replace kitchen and bathroom faucets, shower heads, toilets, drains, supply lines and shut-off valves. I quote first, agree the price with you, then do the work. Downtown condos and basement suites are both fine.
