Here's a link for a job opening. To give some point of reference, from an email I received:

"They certainly do want a capable organist who can play fine preludes, postludes, improvisation, and so on. It's a place where versatility of style will be needed, but also probably open to what higher music can offer. Something such as the Proulx Missa Simplex Gloria could be quite welcome there, for example...."
