Coinsquare Question

I am trying to work with Coinsquare and I have a question about this statement they have on their Fund your account by
Interac Online page:

"Once processed and credited, your funds will be immediately available for trading BUT the total funded amount will be held as collateral and will not be available for withdrawal until the expiry of each unique withholding period (whether this collateral is actual CAD or coins purchased with this funded CAD)."

My question is for those of you who use Coinsquare

1) What is the "Unique withholding period"
2) Has anyone experienced how long this period actually is?

I ask because I would like to be more fluent with buying and selling and not be held up for 10+ days.

Now if you are thinking of recommending QuadrigaCX, please don't, they have banned me from their system for asking on Twitter "is anyone else having issues verifying their account with QuadrigaCX". They considered that abusive.

Thank you,
