Being up in Canada, audio equipment (especially imported) can get pricey.
On the flip side, you have some excellent home-grown speaker companies; two which come to mind and definitely worth looking into are:
PSB and
Paradigm.
There are several others that I am less familiar with.
From PSB specifically, give a listen to the "
Image" and "
Imagine" lines as a good starting point within your budget.
For your subwoofer, I would research the ID companies like HSU, SVS, etc. and see what the shipping/tax situation would be to go to CAN--in general they provide more bang-for-the-looney than other sub options, and there is no advantage to having your sub be from the same company as your speakers AFAIK.
As to your previous AVR/speaker ratio ?: your proposed "
$1k/$3k split" should be very close to a good balance of resources.
