Some random thoughts on a solution

Chlorine _will_ certainly do the trick. But start off wiping a very
diluted solution on a small bit of canvas and 'work it up', since higher
levels might destroy the fabric. ( No idea how fragile your canvas is!)
Rinse after it's done!
First off, on your ( delicate ? ) canvas, maybe try a 'baby nappy cleaner'
like "Nappisan". The other end of the scale is a try and error dilution of
a bottle of 'chlorine bleach', or even swimming pool chlorine which I use
to rid the 'green' on lower bricks on my house, clean a tent canvas from
time to time and use daily in my pool. Chlorine is a #1 algicide that
bleaches and rids the 'green menace' almost immediately. 'Granulated'
chlorine will leave a calcium carbonate residue so probably better to use
liquid, though I find the 'granulated' helps the 'scrubbing' ( on bricks
!...... but this would be a bit 'severe' on your canvas

)
Maybe you could slosh it over with a sponge first _then_ **make sure you
rinse it all off**. A weak solution applied periodically will certainly
keep the 'green' away.
