In a post on the NRC email list, Sheldon Harvey reports CKGM-990 Montreal is testing on their new 690 frequency, with recordings of 990KHz program material. (i.e., not parallel to 990 but the same programs, if that makes sense...)
CKGM is an English-language all-sports station. They've requested CRTC permission to flip languages to French; the CRTC has not yet acted.
No word yet on the 940KHz frequency.
