(I tend to recommend rewriting usernames on MUAs rather than MTAs, but
you did say you used this feature).

This should be a subdomain of blackburnhamlet.ca, and then you shouldn't
need to explicitly set mydomain.

Do you really use these?

Either use canonical maps or this. Both doesn't make sense.

Why not?

Don't set sender_restrictions and complicate things. Put all your checks
in smtpd_recipient_restrictions.
smtpd_recipient_restrictions = permit_mynetworks
			reject_unauth_destination
			check_sender_access hash:/etc/postfix/access

Why not?

> transport_maps = hash:/etc/postfix/transport

Are you routing mail differently, overriding the MX records in DNS?

Why not make this 550?
