Good morning, SabineAC.
Thanks for joining the QuickBooks Community for support. I'd be happy to provide some information.
Since there currently isn't an option to tracking WCB in other provinces in QuickBooks Online, it would need to be tracked outside of QuickBooks. I suggests taking a look at 3rd party Apps in the "Apps" section in your QuickBooks account. I can see how being able to do the calculation and tracking of workers' compensation rates in Atlantic Canada would be a feature that you'd like to see, so I recommend leaving feedback by clicking on the "Gear" icon, then "Feedback". These comments are taken into consideration when our developers design new features and updates for QuickBooks Online. I will also leave this post open for comments from other QuickBooks users to share there experience.
If you have any other questions, feel free to reach back out here.
