I couldn't put my finger on this earlier, but here's a regulatory cite allowing multiple disclosures:
OSC 226.19
If a consumer who has received program disclosures subsequently expresses an interest in other available variable-rate programs subject to 226.19(b)(2), or the creditor and consumer decide on a program for which the consumer has not received disclosures, the creditor must provide appropriate disclosures as soon as reasonably possible . The creditor, of course, is permitted to give the consumer information about additional programs subject to ยง226.19(b) initially .
