Should we invest Cashflows/ Future tax payments

[Warren Marshall]

Hey Guys, 

Cash flow question:   Does anyone invest their cash flow into a liquid tax sheltered investment account? (Canadian investor so I'm thinking TFSA)  The intention would be to invest the bulk of it, and at the end of the year withdrawal enough to pay taxes and leave the rest to grow until we can buy the next property.

My wife and I have a couple Airbnb's that are cash flowing nicely and it seems like a shame to have it sitting in our bank account. For sure I would leave a month or two of reserves in case of emergency but we currently have 8-10 months sitting there.   It would be invested in low risk accounts- I like Wealthsimple but open to other options. 

Thanks in advance, 

Warren
