He added that 70 additional personnel, including 60 "sustained action" firefighters and 10 specialists are arriving as part of a resource-sharing agreement and will be deployed where needed, he said.
All available B.C. firefighters, including 622 contractors, are already engaged across the province, said the B.C. Wildfire Service.
B.C. also has requests in for 290 more fire firefighters, including crews from Australia and New Zealand.
The minister said they may be sent to other provinces needing help, such as Alberta or Saskatchewan, as the resources are coordinated nationwide.
30 new fires each day
The fire danger remains high to extreme throughout B.C., with another 23 fires sparked since Monday.
Wildfire officials are expecting 30 new fires will start each day for the foreseeable future, due to low precipitation and high temperatures that aren't cooling off at night.
Thomson implored smokers to avoid throwing butts out the window and ATV riders to avoid tinder-dry areas.
"Unfortunately it does look like we're in for a long hot summer," he said.
Thomson is providing an update on the wildfire situation along with officials from Vancouver Coastal Health and the B.C. Wildfire Service.
Evacuation orders or alerts are in effect for nine communities.
