** Please be advised that on Monday, August 26 at 5:00 the office will not have any phone, voicemail, or internet service due to an office telecommunications update that our facility will be undergoing.

This means that any messages left from 5:30pm August 23 until Monday, August 26 will not be stored in the voicemail system and the TTNO office will have no record of your call or message due to the upgrade process. We would recommend that you do not leave a message if possible due to this upgrade. If a matter is urgent please email the office at memberships@ttno.ca. We will be able to see your emails when at the office on Wednesday.

The new telecommunications services will be fully operational on Tuesday, August 27 at around 8:30am.

In addition, the office will only be open on Wednesday, August 28 and Thursday, August 29 from 10am to 5pm and closed on Friday, August 30th next week.
