Here's what I do in general:

a) if postmaster@foo.bar.com fails, I try postmaster@bar.com.
   (likewise postmaster@a.b.c.d -> postmaster@b.c.d -> postmaster@c.d)

   (probably won't help for this case, because on.ca is probably not 
   a site, just a domain)

b) try to find the names of contacts elsewhere at that site via
   whois -h ds.internic.net "string"

   (I tried looking for "on.ca" and "ontario", didn't find anything
    that looked to be at that site)

c) use nslookup to find the name of the person responsible for
   administering DNS at that site, and send mail to that person.
   (often it's a DNS problem anyway)

% nslookup
#
# ask my local server where to find info for gov.on.ca.
#
> set query=any
> gov.on.ca.
Server:  UTKCS2.CS.UTK.EDU
Address:  128.169.201.2

Non-authoritative answer:
gov.on.ca       nameserver = govonca.gov.on.ca
gov.on.ca       nameserver = mcu.gov.on.ca
Authoritative answers can be found from:
govonca.gov.on.ca       inet address = 192.75.156.244
mcu.gov.on.ca   inet address = 192.68.229.67
#
# now point nslookup at one of the authoritative servers
#
> lserver govonca.gov.on.ca
Default Server:  govonca.gov.on.ca
Address:  192.75.156.244
#
# and do the lookup
#
> gov.on.ca.
Server:  govonca.gov.on.ca
Address:  192.75.156.244

gov.on.ca       nameserver = govonca.gov.on.ca
gov.on.ca       inet address = 192.75.156.244
gov.on.ca       preference = 0, mail exchanger = govonca.gov.on.ca
gov.on.ca       origin = govonca.gov.on.ca
        mail addr = postmaster.govonca.gov.on.ca
                    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
        serial=940903, refresh=3600, retry=600, expire=3600000, min=3600
govonca.gov.on.ca       inet address = 192.75.156.244
govonca.gov.on.ca       inet address = 192.75.156.244

...so the address is: postmaster@govonca.gov.on.ca.

It might not work, but it's something else to try.

Good luck,
