What this means for your email list
Is a free-provider address a problem?
Not by itself. shaw.ca is a normal mailbox provider used by real people, and mail to it is delivered reliably. The thing to watch is whether the specific mailbox exists, which a domain check cannot tell you, so verify each address.
Sender authentication
shaw.ca has DMARC in monitoring mode (p=none). It collects reports but does not yet block spoofed mail, so the domain is easier to impersonate.
