The subchannels are not licensed for carriage in Canada. They probably never will be. One of the TV service providers in Canada would need to apply to the CRTC for carriage and then it would need to go through hearings with probable objections from other TV services and broadcasters who make money from selling similar content. By the time it's over, one or more the subchannels may have rebranded and would need to reapply.
Why do I think this? I highly doubt Rogers or Bell would ever apply to carry more US stations as they have been dropping US stations for years with no new ones added. It took almost two decades to get FOX approved for carriage in Canada. The CW (and its predecessors) has never been approved and exists as part of a legacy add-on package known known as "US Superstations", some of which switched from independent stations with satellite carriage to OTA CW affiliates years ago. Those stations were originally approved to pad out premium movie packages in order to make them more appealing to Canadians.
