Full excavation, a compacted granular base built for Ottawa frost, and pavers rated for vehicle traffic.
A new driveway starts with digging out the old surface and soil to make room for a proper base. For Ottawa driveways, a 10 to 12 inch compacted granular base is a common standard, placed and compacted in lifts, with geotextile over soft clay where needed.
Driveway pavers should be a vehicular-grade product laid in a pattern that locks under turning tires, such as herringbone. Walkways can use a lighter base but still need proper slope and edge restraint.
The quote lists excavation depth, base material, paver product and colour, edge restraint and what happens to the removed material. Check whether the work touches the City right-of-way near the sidewalk or curb before you sign.
Lift the sunken or heaved section, fix the base, relay the same pavers and compact them level.

Clean out failed joints, refill with polymeric sand, and seal if you want colour and stain protection.
Rebuild leaning block walls and loose interlock steps with a proper footing and drainage behind them.
