To earn CEUs: the CEU code will be displayed on the screen at the end of each session. You must fill out and submit an online CEU form by Apr 5 2021 to earn the credit.

You’ll find the online CEU form on the left when you log into the Whova platform. We recommend reading through our FAQ document (found under "Documents" in Whova) for all the information on the CEU form.

To earn the CEU you must watch the whole session (at least 50 minutes) - we will be cross-checking the watch report metrics from within Whova.

The ISAO TREES VIRTUALLY REIMAGINED conference was packed full of great sessions from local and international speakers.

If you were one of the 570+ who registered, you have until the end of March to watch the recorded sessions, ask the speakers questions, visit the exhibitors and submit your CEU forms! It's all in the WHOVA app.

If you missed out, ISAO Members can also thumb through the FEB/MAR issue of Ontario Arborist to read all about it.

Today is International Women's Day! Join us in Celebrating Women in Arboriculture Ontario (WAO).

We need your help to reinforce arboriculture as a gender-equal industry. Gender-related conversations in arboriculture are on the rise — it's on the mainstream radar from the office to the job site and thankfully, it’s heavily impacting behaviours and assumptions. Stereotypes and bias are widely being called out and addressed — but there’s still much that needs to be done. It’s now up to all of us to #ChooseToChallange and consistently commit to forging a gender-balanced industry.

So many women (and men) have already paved the way for today's female arborists, showing employers, peers and customers alike that they not only have a place in this industry, they excel at it. As industrial athletes/tree climbers, crew leaders, plant health experts, groundworkers, estimators, operations managers, and every other arboriculture role — the women in this industry are making their mark.

We are saddened to share this 2021 International Tree Climbing Competition Update:

With the uncertainty of future shut downs, and the continuation of travel and meeting restrictions globally ISA made the decision to not hold the 2021 International Tree Climbing Competition (ITCC). The safety of our members, competitors, volunteers, and team members remain our priority.

ISA recognizes the importance of this event, and will continue to work with our volunteers, committees, and leaders to ensure we are able to host this event successfully and safely in the future. This is consistent in our decision to host the 2021 ISA International Conference virtually, and is made early in an effort to respect the time and commitment of our competitors, volunteers, and all who make this event possible.

Regional competitions may be possible as non-qualifying events; however, ISA will make determinations at a future date if those events are able to occur this year as more data becomes available. ISA appreciates your continued support during this unique time, and we look forward to hosting these events in the future.

ISA Ontario Members: Save the date for the Annual Meeting of Members which is being held electronically on Thursday, 25 February 2021 at noon.

All current ISAO members will be notified by email when AMM online pre-registration opens. Registration details will also be posted to Facebook and Instagram.
