Installed cost
Tile pricing varies enormously with the tile itself, but the labour is the consistent part: substrate preparation, levelling, setting, grouting and sealing. A resin floor shares the preparation step and replaces everything after it with resin application, which is far less labour per square metre. On a large area the difference is substantial. On a small feature area with an expensive tile, the two can land close together.
The grout is the recurring cost
Tile outlives grout by a decade or more. Grout is porous, it cracks along the movement lines of the substrate, it discolours, and it holds whatever gets spilled on it. Sealing it is a maintenance task that is recommended annually and performed almost never. In a commercial kitchen it is an inspection item at every visit. Over twenty years the regrouting, resealing and repair cost is real money that never appears in the original comparison.
Where tile still wins
Heavy point impact. In a receiving area where things get dropped from height, tile takes the hit better and a damaged tile can be individually replaced, which is genuinely useful. Some heritage and front-of-house spaces want tile for appearance, and running tile front of house and resin in the working areas is a normal and sensible split rather than a compromise.
The residential version of the question
In a basement, a laundry or a mudroom, the comparison usually comes down to feel and appearance rather than cost, because both are affordable at that scale. What tips it in the Okanagan is moisture: tile over a slab with a high relative humidity reading traps vapour under the membrane and fails at the adhesive, which is the same failure that catches vinyl plank. A coating or a polish is a lower-risk floor over an unknown slab.
