Mechanical Insulation Contractor

As of July 1, 2021, the CLR moved to cease clause 23.03 of the 2015-2019 collective agreement on the remittance of .015 per hour collected on all new work in Alberta for the Thermal Insulation Association of Alberta. Therefore, TIAA will no longer be collecting dues via CLR on new work done in Alberta. 

To attain or maintain your TIAA membership, Union Contractors will now be required to make an annual membership fee payment as outlined in the downloadable form:
