Will a bank cancel an approved mortgage/CTC due to Coronavirus

[Mike A.]

We received a CTC on a property a couple of weeks ago and we're awaiting the seller to set a date. The lender, traditional bank, issued a cleared to close to our attorney at that time. Can the bank now cancel the mort. due to these coronavirus fears? We'd lose our deposit as we removed to mort. contingency since we were cleared to close by the bank.
