On January 20th 1994, the worshippers at the Toronto Airport Vineyard Church began to feel the Holy Spirit move them. They began to laugh uncontrollably, collapse to the floor and stagger as if drunk.

Visitors from around the world have come and started revivals in their home churches upon return.
