Hi RenzoM
As SallyE noted, a conversion event won't automatically exit someone from a canvas, that is what the exit criteria are for.
For example, (just winging this), if you had 'Start session' as a conversion metric and then set 'Start session' as an exit criteria I would expect them to exit the canvas when it happened. What I can't confirm is whether the conversion gets registered before or after they exit, so you will need to test this in case they exit and you miss the conversion.
Do you have conversion and exit events set as the same event and they are not exiting? Are they exiting before the conversion or maybe they are exiting as they hit the next step?
I've personally never used this strategy, however, as we tend to follow users through our canvases and measure their conversions over the journey, only exiting them if for example they suddenly change subscription status.
