CS is the easy part, there are table amounts and one parent would then pay the difference (offset) to the other.
Spousal support is a whole other story. It is not granted on a needs only basis there are many factors involved first of which is entitlement. Might be a good idea to start here
Spousal Support Advisory Guidelines
Next you have range (time) and amount. Below is the calculation in its most simplistic form but there are many other factors to take into account. There are some in the forums that would be much better able to assist in making a proper calculation.

"Determine the range of spousal support amounts that would be required to leave the lower income recipient
spouse with between 40% and 46% of the parties’ combined Individual Net Disposable Incomes (“INDI”):
Typical Sole Custody and Shared Custody*:
Payor’s INDI = CSG Income – Child Support (Basic Table* + share of Special Expenses)
– Taxes/Deductions + Gov’t Benefits/Credits – Spousal Support
Recipient’s INDI** = CSG Income – Child Support (Notional Basic Table* + share of Special Expenses) –
Taxes/Deductions + Gov’t Benefits/Credits + Spousal Support"
* For shared custody, the full amount of Basic Table Child Support according to the CSG is deducted from each party’s INDI in order to
determine the setoff amount under s.9(a) of the CSG (ie. the difference between the parties’ respective basic Table amounts). The
recipient’s Child Support is accordingly no longer notional in a shared custody arrangement. In light of the S.C.C. decision, Contino v.
Leonelli-Contino, 2005 SCC 63, the setoff amount may need to be adjusted in accordance with s. 9(b) and (c) of the CSG.
** The child support paid by the payor to the recipient is not included in the recipient’s INDI."
