1. Executive Summary

This report relates to AM broadcasting aspects of Industry Canada's response to CRTC Public Notice 2001-10, Report to the Governor in Council on measures to ensure that the residents of the Greater Toronto Area receive a range of radio services reflective of the diversity of their languages and cultures. It contains the author's analysis of the engineering report which the CRTC commissioned from Imagineering Limited on this topic, as well as the results of his own studies.

The Imagineering report reviews all current radio broadcasting bands and provides recommendations on each. The following table contains a summary of the possibilities in the AM band identified by Imagineering or the author:

Channel Potential Coverage (km in max. dir.) Comments
Day Night
  1. Footnote * Protection requirements preclude operation near lakeshore or serving downtown Toronto. Could operate at or slightly above LP parameters to serve communities not near Lake Ontario, but would displace LP station CFYZ serving Pearson Airport
  2. Footnote ** From Island site, cannot serve west part of GTA day. Could use 1480 or 1500 day.
  3. Footnote *** There is a possibility that five stations could be cosited 20 kHz apart from 1610 to 1690 kHz. Two relatively simple studies, outlined in Appendix 2, are required to determine if this is practical. In case the 20 kHz cositing is not practical, it is recommended that the 1670 kHz applicant be requested or required to revise his application to 1650 or 1690 kHz to permit an additional station in the GTA.
790 70 11 Suitable site unlikely to be found. Could operate at lower parameters if colocated with existing station near market.
940 70 2 Requires exception to night-time protection rules. Siting would be difficult. Could operate at lower parameters if colocated with existing station near market. Mutually exclusive with 950.
950 80 30 Former Barrie station. Needs access to port lands site.
1100 50 0 Day only. Mutually exclusive with 1110.
1110 120 2 Can share Toronto Island site
1190 90 0 Day only. Mutually exclusive with 1200.
1200 80/120 10/35 From Oakville site/ from port lands site
1280 0Footnote * 0Footnote *  
1470 Footnote ** 25Footnote ** Formerly used by CHOW Welland and fully equipped site available for sale. Serves most of GTA daytime, but subject to interference at night. Moving closer to Toronto is possible if CHKT's Toronto Island site can be shared.
1480 40 3 Formerly used by CKAN Newmarket; site dismantled. Difficult to serve much of GTA at night. Mutually exclusive with 1470 and 1500.
1500 85 6 Siting difficult for night operation. Day can site anywhere and could have 60 km non-directional service. Mutually exclusive with 1480.
1580 70(ND) 4 Requires exception to night-time protection rules.
1610Footnote *** 70 12–25 LP station CHEV would be displaced. Markham application would serve only NE corner of GTA night
1630Footnote *** 70 12–25  
1650Footnote *** 70 12–25 May be incompatible with application on 1670.
1670Footnote *** 70 12–25 East York application could switch to 1650 or 1690 to ensure availability of third channel
1690Footnote *** 70 12–25 May be incompatible with application on 1670.

Siting Considerations

Good coverage of the GTA, particularly downtown Toronto, requires a lakeshore or Toronto Island site for the high AM channels. Multilingual stations CHKT on 1430 kHz and CHIN on 1540 kHz currently use Toronto Island sites, which could potentially be shared with new stations on two other channels. (See Appendix 1, a letter from J. Gordon Elder, P. Eng., who designed and built these two stations.) In addition, the port lands and Leslie Street Spit area shown in Figure 2.3c of the Imagineering report would be a very good location for at least two other channels below 1600 kHz, as well as any or all of the five available channels in the expanded band.

The white box in the map below shows the approximate boundary of the GTA.
