I agree, I thought Ottawa had an anycast node from the ISC (f) root
[root at wpgnetsvc02 ~]# traceroute f.root-servers.net
traceroute to f.root-servers.net (18.104.22.168), 30 hops max, 40 byte packets
9 gw-isc.torontointernetxchange.net (22.214.171.124) 58.612 ms 22.422 ms
10 f.root-servers.net (126.96.36.199) 23.249 ms 23.457 ms 23.758 ms
I don't know about any of the gTLDs (.com, .org), but the ccTLD for .ca is
in Canada, I don't know the locations:
[root at wpgnetsvc02 ~]# dig foo.ca @f.root-servers.net
;; AUTHORITY SECTION:
ca. 172800 IN NS CA04.CIRA.ca.
ca. 172800 IN NS CA05.CIRA.ca.
ca. 172800 IN NS CA06.CIRA.ca.
ca. 172800 IN NS NS-EXT.ISC.ORG.

ca. 172800 IN NS CA02.CIRA.ca.
ca. 172800 IN NS CA03.CIRA.ca.
