The satellites are at capacity. The Canadian service just doesn't offer all the channels that are available. The Canadian radios also don't offer all the features of seemingly identical US radios. I don't know if that impacts channel availability, yet, but it does affect package options and has for years.
Here is the simple explanation (ignoring XM 2.0.) Sirius and XM channels are on two adjacent frequency bands. They also use different technologies, making each radio unusable on the other band (or service.) Let's say each band can carry 240 channels. Of those, let's say 120 channels are identical, duplicated channels. Under that scheme, dual band/dual technology radios can increase channels on a single radio to 360. By using the same technology across both bands, SiriusXM could offer 480 channels on a single radio by eliminating the duplicated channels and creating 120 new channels. SiriusXM was prevented from combining the two bands for several years under the US merger agreement. When that expires, they can combine the two bands under a single technology and increase effective capacity.
The dual band/dual technology radios were also mandated under the US merger agreement but they are more difficult and costly to produce. A single technology radio is the way to go in the long run.
