North Vancouver Fire had to use an inflatable raft to get to a stranded hiker and his dog at the bank of the Seymour River.
Assistant chief Jim Bonneville says homeowners across the river called 9-1-1.
"There were quite a few homeowners on the opposite side of the bank so with him calling for help our crews were there fairly quickly."
Bonneville says there is a lengthy trail system with many unmarked routes, and they believe the man simply got lost as it got dark.
Both the man and his dog were cold, but unharmed.
