After being offline for several hours, Canadian IOUCentral.ca is now online again, but with limited functionality. That means that currently no loan listing and bidding is possible.

From the website:

Why Is IOU Central Operating With Limited Functionalities?
IOU Central is now operating with limited functionality while we resolve a regulatory matter. IOU Central is acting in a very new area. We are the first in Canada, although similar models are operating under similar regulatory environments in the US and the UK. We are modeled on those innovative enterprises. We are committed to working with all the relevant regulatory bodies in order for us to continue to offer this service to borrowers and lenders. We will take all measures necessary to ensure we are working in full compliance with all regulations.

When Will IOU Central Be Fully Operational?
We will notify all our users by email when the site is fully operational. If you are not already a user, you may register with us and we will notify you by email when the site is fully operational.
