When/if this is released in Canada, it will also be released in the US.
The reason is because Warner Bros. are the exclusive distributor for all of North America (including Canada) for Doctor Who releases. So, Canada will not be getting a separate release. They will have the same one that we will get.
Don't worry, you can bet your TARDIS that there will be a R1 release of the "new" Doctor Who. Just when it will be, whether November or later, or whether it will be the same as the UK boxset, or (hopefully not) the current no-frills UK individual releases, remains to be seen.
