The July 11 fire at the Shaw Communications' headquarters caused the outage of a data centre that supports a variety of provincial services.
Most were restored two days later, but the motor vehicle registry and land titles data needed more time to restore and test to ensure they were stable and working properly.
Drivers with licences that expired on or after July 1 were granted an extension, which will stay in place until July 31 to allow time for motorists to renew their licences.
Service Alberta Minister Manmeet Bhullar says in a release that government and IBM technicians worked around the clock to get services back up and running.
The government says now that they have been restored, an internal assessment will be done to determine what happened and to make possible changes.
Peter Bissonnette, president of Shaw Communications, apologized for the impact the outage caused.
"We know many people have been affected by this incident in different ways, and we are sorry for the impact caused," Bissonnette said in a news release Tuesday.
"We understand the frustration that this incident has had on our customers, tenants and many Albertans as a result of last week's fire."
The release said that 900 Shaw Court employees will be temporarily located for several months at seven other buildings in Calgary while damage to the building is fixed.
Shaw says the media, customers and the general public can stay up to date on operations, customer service and other important information via updates on www.shaw.ca.
"We've been putting our customers first since day one, will continue to do so and we are fully open for business," said Bissonnette.
"We again thank everyone for their patience and want to ensure the community that we will work tirelessly to make this right."
