Looking at the specs for the Jaguar Portables Ottawa uses, the frequency will between 851mhz and 870mhz. Based on what other simplex 800mhz freqs seam to be for Ontario trunked users I would suggest 866-868.9mhz. Try; 866.2500,868.2500, 868.3500,868.4500, and 868.6000mhz they seam to be common simplex in Ontario. I will see what I can dig up as well but these are very low power portables.
