Snow is being brought to the Cypress Mountain venue – that will host the freestyle and snowboarding events – from the Allison Pass 93 miles away.
“We simply cannot have a start that is affected by weather,” said organising committee chief John Furlong.
January temperatures have hit a record average high at 7.2C degrees.
As well as importing snow from other areas, organisers have been pushing down snow stockpiled at higher altitudes and using bales of hay to build a base on the race courses.
The venues are expected to be ready for the Games’ opening on 12 February.
