I work with Uber rideshare/Eats and Skip-the-dishes. Should I create 2 different business? How may I input my vehicle's expenses in both businesses - split half/half? Thx

You would fill out 2 separate Self-Employment forms for each as they are different services. As for your vehicle expenses would be calculated based on the amount of driving you do for each business. 

Remembering to keep a detailed record of all receipts and transactions for each, as the CRA may request them later.

Here is a TurboTax Guide for Uber drivers to review if needed: https://bit.ly/2TfNgVP
