Frequently Asked Questions

The annual licence-holder fee was last increased in 2008.

At its February 2019 meeting, Council approved repealing section 59 of By-Law No. 1 to remove its obligation to always seek member confirmation to increase the annual licence holder fee. Section 59, which was created in 2011, had been determined to be legally invalid, as it infringed on Council’s authority to determine on a case-by-case basis whether to seek member confirmation of by-laws passed by Council. The repealed section of the bylaw read as follows:

59. Council shall seek confirmation by the members of the association of a bylaw passed by the Council pursuant to the act pertaining only to annual fees for licence holders 

Council still retains its full authority to decide on passing future bylaw changes, with or without seeking a member confirmation to vote. Council has the authority under section 8(2) of the Professional Engineers Act to pass any bylaw within its bylaw-making powers unless under section 8(3) Council specifies that the bylaw be confirmed by a majority of the members voting on the bylaw.

Council also decided to approve the approximately 20 per cent fee increase under section 8(2) of the Professional Engineers Act without seeking member confirmation of the bylaw change.  

The bylaw changes approved by Council in March 2019 and that become effective May 1, 2019, are one-time fee increases to catch up with inflation since 2008. They exclude for the time being two new fees approved by Council in November 2018. These include: interviews to waive technical examinations, and a $10 credit card convenience fee. These new fees may be implemented later.
