Welcome to the community!
What you're looking for is a temporary suspension. Fido does offer a temporary suspension of 2 to 12 months for a reduced monthly rate of $7 per month. However, the suspension is only available on accounts without an agreement (see here). You should also note that the suspension can only be applied after your current billing cycle has ended.
If you're eligible for the temporary suspension, you would need to contact customer service to have it set up. Alternatively, you might consider sending @FidoSolutions a PM. Once they verify some information, they will also be able to access your account.
Hope this helps 😀
