She said the donors had been "tremendously generous" with the amount donated so far.
The donations are typically in the hundreds of dollars but one donor gave $1500.
Chief fire officer Andrew Norris said at least half of his firefighters were self-employed and others took time off work to fight the Port Hills blaze.
He said they were all surprised by the gesture.
"The donations for their pay is not usual, but most welcome by the guys and girls who lost income," said Norris.
It is the first time he had encountered a situation like this so was unsure how they would split the money between the firefighters.
However, it will definitely be given to the firefighters as intended, he said.
"We are truly grateful to the people that set [the page] up and to the donors as well."
