A temporary field authorization gives short term approval to work on public land.
What This Approval Actually Means
Anyone working near energy sites or public land projects has probably heard this term before. It used to be called TFA, but the AER changed the name back in August 2019. Many companies still use the older term, depending on the type of work they do.
Temporary Field Authorization Basics
A temporary field authorization allows a person or company to carry out work in one place for a short period. Regulators issue it when a full permit is not needed. It suits quick jobs such as surveys, exploration work, or small land use changes.
Who Typically Needs This Approval
Energy companies, land surveyors, and construction crews are the most common applicants. Anyone needing short term access to public land, whether for exploration, a pipeline check, or a small clearing, usually starts with this same basic process.
Why People Apply for This Approval
Most applications fall into three groups. Some come from client requests for small clearings on public land. Others involve short term changes to an existing land disposition. The rest simply authorise a suitable land use for a set period of time.
How Long It Takes
Processing usually takes about five business days for a temporary field authorization, though this can change. It is worth checking the timeline spreadsheet for the latest figures before you apply, since processing speed can shift with demand and season.
Submitting Through OneStop
Applications usually go through OneStop, where you upload shapefiles along with any supporting documents the reviewers might need. This spatial information helps reviewers understand exactly where and how the work will take place before granting approval.

The Manual Application Route
Projects outside OneStop, such as oilsands exploration, coal exploration, or geophysical exploration, still use the older manual form. You will find it listed under Public Lands Act Forms on the regulator’s website, ready to download and complete by hand.
What Happens During Review
Every temporary field authorization goes through spatial analysis and gets checked against OneStop validations and existing business rules. If anything needs a closer look, the file gets flagged and moved forward for a more detailed technical review.
Expert Review and Extra Information
Flagged files land with an AER subject matter expert for technical review. Do not be surprised if a supplemental information request comes back asking for more detail. This extra step simply helps reviewers make a fair and well informed decision.
Common Mistakes to Avoid
Missing shapefiles, incomplete forms, and vague project descriptions cause most delays. Double check your documents before submitting, and keep a copy of every file you send, since reviewers may ask for the same details again during a supplemental request.
Approval, Appeals and Reapplying
Reviewers either approve, close, or deny each temporary field authorization, and every decision gets posted on the Publication of Decision page. If yours is closed or denied, you can appeal, or simply reapply once you fix whatever caused the problem.
Everyday Uses Beyond Regulatory Filings
This kind of temporary field authorization also covers ordinary construction or maintenance work in a public right of way, like a street or sidewalk. It sets out the location, the duration, and any conditions that keep the work safe and controlled.
Why Professional Guidance Helps
Balancing proper oversight with practical work is not always simple. Having CWP Environmental professionals guide you through the process can save time, reduce mistakes, and help you avoid delays caused by missing paperwork or unclear project details.
What Facebook and Reddit Users Say
On Facebook groups for land and energy workers, people often ask how long a temporary field authorization actually takes to process. Reddit users in similar threads say the OneStop system feels simple once your shapefiles and paperwork are ready.
Final Thoughts
A temporary field authorization keeps short land projects simple, quick, and properly approved.
