Faucet installation in Ajax most often means a stainless double-bowl sink with four holes in the deck, the standard fit in the 1990s and 2000s subdivisions around Westney and Harwood. The old single-lever tap and its side spray came as a pair, and the modern pull-down replacing them only needs one hole.
So the spare holes have to be dealt with properly. I replace faucets, shower heads, toilets, drains, supply lines and shut-off valves, and I quote before I start.
Almost every Ajax kitchen built in the 1990s and 2000s has the same four-hole stainless sink: tap, two spare, and a side spray that has probably stopped working. A pull-down faucet fills one hole, which leaves two or three staring at you. I fit a soap dispenser, an air gap or a matching cover plate so the deck looks intended rather than patched. Pickering Village is the exception, with older houses, smaller sinks and shut-offs that need replacing before the tap can come off.
