Registered Product vs Licensed Exterminator
PMRA registration
- Product federal approval
- Current label controls uses
- Not personal authorization
MECP licence
- Person authorization
- Category-specific scope
- Provincial conditions apply
Need both legal pathways
Legal Use Picker
- Product unregistered federally→Do not use(Confirm PMRA registration)
- Ontario class unclear→Check current federal designation(Then provincial class)
- Site absent from label→Do not apply(Customer request cannot expand use)
- Licence category mismatched→Do not perform(Confirm correct category)
- Cosmetic land use→Check Allowable List/exception(Licence alone insufficient)
Core vs Category Exam
Core Manual
- Common safety concepts
- 50 closed-book MCQs
- One hour
Category module
- Specific licence class
- 50 open-book MCQs
- One and half hours
Pass both for certification
Ontario Classes
- Class A
- Federal manufacturing designation
- Class B
- Federal restricted designation
- Class C
- Federal commercial designation
- Class D
- Federal domestic designation
- Class E
- Specified neonic-treated corn/soy seeds
- Licence category
- Limits authorized extermination type

- Check Allowable List or exception
Certification vs Licence
OPT&C certification
- Pass Core and category
- Letter after exams
- Apply within one year
MECP licence
- Provincial authorization
- Class limits work
- Five-year term
Certificate alone cannot authorize work
Label Gate
SLUM: site, label, use, method
Label vs Safety Data Sheet
Approved label
- Registered use directions
- Rates and buffers
- Product-specific first aid
SDS
- Hazards and handling
- Storage and emergency details
- Does not expand uses
Follow both applicable requirements
Label and PPE Picker
- Similar product names→Match PCP registration number(Read current label)
- Mixing concentrate→Use mixing-specific PPE(Check label section)
- Tank mix proposed→Check both labels(Follow all restrictions)
- Entry after treatment→Check labelled REI(Limit access accordingly)
- Buffer near water→Follow exact label buffer(Equipment alone cannot cancel)
Label Check
- PCP number
- Match current registered product
- Registered site
- Use only listed site
- Target pest
- Check label permission
- Application rate
- Never exceed label directions
- Application method
- Match label instructions
- Buffer zone
- Follow stated conditions
- REI
- Observe labelled entry restriction
- First aid
- Follow product-specific statements
- SDS
- Supplemental hazard information
Acute vs Chronic Exposure
Acute
- Short exposure
- Immediate or delayed effects
- Compare acute tests carefully
Chronic
- Repeated/long exposure
- Longer-term effects
- Control cumulative exposure
Time pattern differs
Exposure and First Aid
- Dermal
- Skin contact route
- Inhalation
- Breathing exposure route
- Ingestion
- Swallowed material
- Ocular
- Eye contact route
- Acute
- Short-exposure effect
- Chronic
- Repeated/long-exposure effect
- Lower LD50
- Higher acute toxicity; comparable tests
- Suspected poisoning
- Follow label; seek medical advice
- Medical handoff
- Bring label and PCP number
PPE by Task
- Mixing concentrate
- Check task-specific label PPE
- Chemical gloves
- Match label-resistant material
- Eye protection
- Follow splash-risk label directions
- Respirator
- Use specified type and fit
- Dust mask
- Not automatic respirator substitute
- Damaged PPE
- Replace before handling
- Contaminated clothing
- Separate; clean or discard
- Hand hygiene
- Wash before food or drink
Calibration Distinction
Area × rate = product; volume = mixture
Product Rate vs Carrier Volume
Product rate
- Concentrate per area
- From current label
- Determines pesticide quantity
Carrier volume
- Mixture per area
- Set through calibration
- Determines spray volume
Never equate mixture and concentrate
Application Decision
- Pest unconfirmed→Identify and monitor(Avoid automatic spray)
- Below action threshold→Continue monitoring(Unless other trigger applies)
- Nozzle worn→Replace and recalibrate(Rate may change)
- Weather threatens drift→Delay application(Recheck current conditions)
- Sensitive habitat nearby→Apply label protections(Check buffers and timing)
Formulation and Mixing
- Ready-to-use
- Apply as supplied when labelled
- Concentrate
- Dilute exactly as labelled
- Wettable powder
- Agitate as label directs
- Tank mix
- Check every applicable label
- Carrier volume
- Spray mixture, not concentrate
- Product rate
- Label amount per area
- Water source
- Prevent back-siphoning
- Nozzle wear
- Changes output and droplets
Calibration Math
- Area
- Length times width; convert units
- Mixture needed
- Volume per hectare times hectares
- Product needed
- Label rate times hectares
- Worked mixture
- 200 L/ha × 2ha = 400L
- Worked product
- 1.5 L/ha × 2ha = 3L
- Output check
- Measure actual nozzle flow
- Speed change
- Recalculate area application rate
- Pressure change
- Recheck output and droplet pattern
IPM Loop
IMAC: identify, monitor, act, check
IPM Sequence
- Identify
- Confirm pest before control
- Monitor
- Measure pest pressure
- Threshold
- Control justified at trigger
- Prevention
- Reduce favourable pest conditions
- Nonchemical
- Consider exclusion or sanitation
- Chemical choice
- Labelled option when justified
- Resistance
- Vary suitable modes and tactics
- Recheck
- Measure control outcome
Drift vs Runoff
Drift
- Airborne off-target movement
- Wind/inversion concern
- Droplet and buffer controls
Runoff
- Waterborne off-target movement
- Rain/slope concern
- Waterway protection
Pathway changes controls
Drift and Water
- Wind direction
- Check sensitive downwind areas
- Wind speed
- Use current site conditions
- Inversion
- Fine droplets may linger
- Buffer
- Follow current label conditions
- Runoff
- Avoid off-site water movement
- Pollinators
- Follow bloom and bee warnings
- Spray quality
- Match label droplet direction
- Sensitive site
- People, water, crops, habitat
Storage and Transport
- Original container

- Damaged container
- Use compatible labelled replacement
- Food separation
- Prevent food/feed contact
- Secure storage
- Limit unauthorized access
- Vehicle load
- Secure upright containers
- Rinsate
- Manage under label and rules
- Leftover mix
- Use/dispose only as allowed
- Empty container
- Check label before rinsing
Spill Priorities
PACT: people, area, contain, tell
Exposure or Spill Response
- Worker collapsed in hazard→Protect rescuers; call 911(Move only if safe)
- Skin or eye exposure→Follow label first aid(Seek help as directed)
- Spill threatens people→Isolate area; call 911(If immediate danger)
- Spill source accessible→Stop only if safe(Contain away from drains)
- Reportable Ontario spill→Call Spills Action Centre(Notify municipality and known parties)
Spill First Moves

Common Traps
Federal vs provincial
PMRA registers products ≠ MECP licences Ontario exterminators
Core vs authorization
Core pass is partial certification ≠ Licence authorizes covered work
Class E vs category
Class E means treated seeds ≠ Exterminator category defines work
Label vs SDS
Label limits registered use ≠ SDS adds safety details
LD50 comparison
Toxicity: inherent harm potential ≠ Exposure: amount reaching person
Buffer vs nozzle
Drift controls reduce risk ≠ Mandatory buffer still applies
Mixture vs product
400 L may be spray mixture ≠ Product follows label rate
Rinse vs always
Rinseable container: follow label/rules ≠ No-rinse label: do not rinse
Spill size vs reporting
Reportable spill: notify required parties ≠ Small spill: assess legal trigger
