The inferno's progress prompted authorities to take new emergency measures, ordering the evacuation of 24,000 people in the region including the town of Williams Lake which is home to some 11,000 people, reported public broadcaster CBC.
Some 60 percent of affected residents have already left their homes.
Authorities estimate that around 17,000 people had already evacuated before the latest orders as wild fires sparked by hot dry weather prompted a state of emergency to be declared on July 7.
Navi Saini, a spokeswoman for the province, said there were currently 161 wildfires active as of Sunday.
"Great news! All evacuation warnings for the #AlamoFire have been lifted. There is fire equipment still in the area working - use caution," the official account for Cal Fire tweeted.
The Whittier fire, which began on July 8 and stretched across 18,015 acres and has burned down almost 2,000 structures was 36 percent contained, according to the agency.
