Yes, but CKCO (as it was then) would have been limited to 5 kW under
NARBA.

According to the Canadian Communications Foundation's database, CKOY
(as it was in the relevant era) upgraded to 50 kW in the early 1960s.
Under the bilateral frequency coordination arrangements at the time, I
believe the FCC would have demanded that CKOY protect the US border at
the same electric field intensity as the old 5-kW facility (whereas a
new station on 1310 would only have required contour protection).
