What's the relationship between the PCA and the CanRC?

This morning I finally managed to find the North Ridge Presbyterian Church (PCA). It was a little hard to find, as it does not have a building of its own, has no outside sign (this apparently is a also a restriction of their rental agreement as in the St. Albert CanRC), and is not a massive congregation.

I've had a little trouble finding anything official regarding the relationship between the PCA and the CanRC other than one rather ambiguous comment. However, the PCA is a member of NAPARC, an organization which includes as members the RCUS, the OPC, and the ERQ (which the CanRC considers sister churches). Apparently, through NAPARC there is a membership transfer agreement in place between these churches. I also heard when talking to people after the service that the pastor of the other PCA in town would be preaching at the local URC this evening, so the relationship between the URC and PCA also appears good (at least locally).

As far as names that you might recognize, according to Wikipedia the denomination's membership includes such individuals as R.C. Sproul, Ligon Duncan (president of the Alliance of Confessing Evangelicals), Marvin Olasky as well as (musically) Steven Curtis Chapman and at least one member of the group Caedmon's Call. These are just a few, though, of the denomination's 330000 members in around 1500 churches.

I've seen some churches in which there is modern music but no little to no theological depth, yet in this church modern instrumentation was using while still singing songs with meaning to them. This was also a church unafraid of modern technology. While hymnals were still distributed and lyrics to any songs outside the hymnals were printing in the liturgy sheet, an LCD projector was used to project lyrics.
