The majority of the closures will take place this year, while 55 stores that include a post office counter will close next year.
Morrisons bought the McColl's chain out of administration in May but the deal was not cleared by the competition regulator until last month.
It said that every affected worker would be offered alternative employment at a nearby McColl’s store, Morrisons store, logistics operation, or foodmaking centre.
McColl's currently trades from 1,164 stores, 286 of which trade under the Morrisons Daily fascia.
The chain has annual turnover of about £1.2 billion (€1.38 billion), representing about 0.8% of the UK grocery market.
Morrisons' plan is to have more than 1,000 stores trading as Morrisons Daily within two years.
It said it will invest significantly in the McColl’s business over the next year, improving the chain's product range and pricing position.
In September, Morrisons reported a halving of its third-quarter core earnings, as underlying sales fell 3.1% against the backdrop of a cost of living squeeze.
Morrisons said the fall reflected 'a number of temporary and transitional factors', some of which it expected to reverse in its fourth quarter, and a change to its year-end.
The group differs from its main rivals in that it also has its own manufacturing operations, which also experienced unprecedented inflationary pressure during the reporting period.
