Professional Foresters Act Update

See the link in our bio »

At the start of January 2021, the ISAO chapter was made aware of proposed changes to the Professional Foresters Act, 2000, S.O. 2000, c.18, “the Act”, and Regulation 145/01 “the regulation”.

This legislation regulates the scope of practice of Professional Forestry within the Province of Ontario. The Ontario Professional Foresters Association (OPFA), is the licensing body. The proposed changes to the Act, if approved, would have potentially devastating impacts to the arboricultural industry, and certified arborists practicing in all sectors.

ISAO Webinar Series FOR KIDS!!! Register NOW! See the link in our bio.

Thu, Jun 17, 2021 9:00 AM - 10:00 AM EDT

The incomparable Professor Elwood Pricklethorn (PEP) will be speaking to primary school-aged children, in English, all about his favourite topic in the whole wide world -TREES! - “The things we can do to help an urban tree. Let’s make a list!”

PEP will focus on the simple things that we can all do to help urban trees thrive and stay alive. It is often said that trees in natural forest or woodlot need little help or human intervention to thrive, but when we plant trees in our town and cities, they often need extra help and care.

By seeing trees through the Professor’s eyes and his green-coloured lenses, you will see the trees around you in a very different way. Through his fast paced and engaging presentation style, we will learn to respect and care for the very trees that help us in countless ways. Please tune in to this funny and educational, 15-minute webinar, for children as PEP leads an interactive discussion about how we can all help with some simple ways of giving urban trees a better chance for survival.

The OTCC Committee wishes to inform everyone that once again we have unfortunately been forced to cancel the Ontario Tree Climbing Championships. With the constantly changing COVID landscape coupled with the enormous logistical challenge to execute an event in accordance with current health and safety standards, and the decision by the hosting city to not grant permits for special events this season, the Committee was left with no alternative.

We appreciate your understanding of this decision and look forward to resuming this amazing industry event in 2022. In the meantime, the Committee is brainstorming ideas for virtual events to host which would still provide a venue for the industry to come together so stay tuned for more details!
