MEDIA RELEASE: CAA Survey Reveals Substance Use, Particularly Cannabis, is on the Rise Both Recreationally and Behind the Wheel

New findings from a recent survey conducted by CAA Manitoba (CAA MB) highlight a concerning trend: substance use, particularly cannabis, is on the rise both recreationally and behind the wheel.


“Cannabis is more accessible than ever, and that means more Manitobans are not only choosing to drive after consuming it but are also getting behind the wheel soon after and expressing increased confidence in their ability to do so,” says Ewald Friesen, manager, government & community relations for CAA Manitoba.


The data shows that 24 per cent of drivers admitted to consuming cannabis before driving, which is up six per cent from last year, while ten per cent of Manitobans reported driving after consuming cannabis in the past few months, a three per cent increase from 2024. Among cannabis-impaired drivers, most (63 per cent) say they drove within three hours of consumption, which is up 10 per cent from last year. Over a third of cannabis-impaired drivers acknowledged feeling high while driving.


In addition to the survey conducted by CAA MB, a recent study with funding support from CAA, conducted by the University of Saskatchewan, examined 50 drivers aged 19 to 30 to assess how consuming edible cannabis influences collision risk. This age group of young drivers, identified as having the highest crash rates and a greater tendency toward risky driving behaviour, offers new insights into the impact of cannabis on driving.


Drivers often have a false sense of confidence when driving high.


This study examined how consuming edible cannabis affects collision risk. Findings indicate that critical driving skills, including reaction time, lane discipline, and speed control, were impaired even shortly after consumption. Contrary to popular belief that cannabis edibles take hours to take effect, this study shows that impairment is evident 90 minutes after consumption. When asked if they felt safe to drive after consuming edibles, only four per cent felt safe getting behind the wheel 90 minutes after eating an edible cannabis product.


What is interesting about this is that in a controlled environment, young drivers feel unsafe driving under the influence of cannabis. However, the study conducted by CAA MB shows that drivers often have a false sense of confidence when they have driven high in the past.


“This study marks an important first step in understanding how cannabis edibles impact driving performance,” adds says Friesen. “Too often, decisions about whether someone is fit to drive are made in the moment, relying on judgment rather than evidence. Cannabis impairment studies like this are essential. Each one brings new learnings that help us refine our approach and ensure that safety is never left to chance.”


According to CAA Manitoba’s data, more drivers have reported feeling confident in their driving ability (77 per cent), which is up ten per cent from 2024. More drivers this year (33 per cent) also say that they are unsure about how much cannabis is needed for effects to kick in, up six per cent from 2024. Alarmingly enough, more than half of Manitobans are unaware that the penalties associated with driving under the influence of alcohol, drugs, or a combination of substances are

the same.


“Drivers may face enhanced roadside sanctions, including an administrative penalty of $700, vehicle impoundment, mandatory Ignition Interlock participation for one year, an impaired driver assessment and movement of 10 levels down the Driver Safety Rating scale,” says Friesen. “Depending on the severity of convictions, impaired drivers may be charged further under the Criminal Code of Canada.” 


This holiday season, CAA Manitoba is asking that those who do consume cannabis, alcohol or other drugs to plan ahead by making alternate arrangements, such as a designated driver or using a rideshare service, to get home safely.  


Methodology CAA MB
The online survey was conducted by DIG Insights from June 27 to July 14, 2025, with 514
Manitoba drivers aged 19 and older. Based on the sample size of n=514 and with a confidence level of 95 per cent, the margin of error for this research is +/- 3%.)
Methodology of University of Saskatchewan study
The study collected extensive data from 50 young adult drivers (aged 19–30), resulting in 250 assessments across multiple realistic driving scenarios using a simulator after consuming a 10mg THC edible.

MEDIA RELEASE: Hamilton's Barton Street East is named CAA’s Worst Road in Ontario for a third time

Ontarians have spoken, and the 2026 CAA Worst Road in Ontario is Barton Street East in Hamilton. This year marks the third time Barton Street East has taken first place. The 2026 list reflects feedback from thousands of Ontarians who experience the province’s roads every day, highlighting the roads drivers say need urgent repair and calling on all levels of government to prioritize investments for safer infrastructure. “The CAA Worst Roads campaign gives Ontarians a voice and helps shine a light on the roads that need attention most,” says Brian Pirvu, government relations consultant for CAA South Central Ontario. “When people speak up, it helps drive action and ensures governments understand where investments are needed to keep communities safe and moving.” Four of this year’s Worst Roads are located in Toronto, underscoring ongoing challenges in some of the province’s busiest corridors. Across both the city and the province, road users commonly cited potholes, poor maintenance, and uneven surfaces as top concerns affecting safety and mobility. “Reliable infrastructure isn’t just about convenience; it’s about safety, affordability and quality of life,” says Pirvu. “Investing in roads helps reduce repair costs for drivers and ensures people can get where they need to go safely.” CAA’s annual Worst Roads campaign helps spark dialogue with municipal and provincial governments and prioritize infrastructure improvements where they are needed most. “CAA will continue to advocate for stable, predictable investment in road maintenance and long-term solutions to address Ontario’s growing infrastructure needs,” adds Pirvu. Ontario’s Top 10 Worst Roads for 2026 1. Barton Street East, Hamilton 2. Hurontario Street, Mississauga 3. Notre Dame Avenue, Greater Sudbury 4. Sider Road, Fort Erie 5. Steeles Avenue East, Toronto 6. Sheppard Avenue West, Toronto 7. Panache Lake Road, Greater Sudbury 8. Bathurst Street, Toronto 9. Unwin Avenue, Toronto 10. 6th Line, Innisfil Ontario’s Worst Roads by Region for 2026 • Toronto Region - Steeles Avenue East • Halton, Peel, York, Durham Region - Hurontario Street, Mississauga • Hamilton Region - Barton Street East • Ottawa Region - Carling Avenue • Central Region - 6th Line, Innisfil • Eastern Region - Leveque Road, South Frontenac • Western Region - Ira Needles Boulevard, Waterloo • Southwestern Region - Blackwell Sideroad, Sarnia • Niagara Region - Sider Road, Fort Erie • Northern Region - Notre Dame Avenue, Greater Sudbury The annual list is based on nominations submitted by Ontarians and provides decision-makers with a snapshot of public priorities. Roads that appear on the list often receive accelerated attention as governments respond to community feedback. The Residential and Civil Construction Alliance of Ontario (RCCAO) has verified Ontario's top 10 list and is a technical partner in the CAA Worst Roads advocacy campaign. "People across Ontario have spoken. The CAA Worst Roads campaign gives voice to residents who experience firsthand the impact that deteriorating roads and aging infrastructure have on our lives daily," says Nadia Todorova, executive director at RCCAO. "The results underscore the importance of sustained investment in state-of-good-repair infrastructure.” For more information and regional results, visit caaworstroads.com.

Provincial Trunk Highway 34 is Named the Worst Road in Manitoba for the Second Year in a Row

Provincial Trunk Highway 34 (PTH 34) has been named Manitoba’s worst road for the second year in a row, according to the results of the 2026 CAA Worst Roads campaign. The Pembina Valley highway, located west of Winnipeg, has previously appeared on the provincial top ten list seven times, and this is the second consecutive year it has claimed the top spot. Manitobans who nominated PTH 34 did so because of potholes, poor maintenance, and uneven road surfaces. “The roads on this list reflect what Manitobans experience every day,” says Ewald Friesen, manager of government and community relations for CAA Manitoba. “Manitobans want roads that are safe, reliable and properly maintained, whether they live in Winnipeg or in a rural community. This year, 711 roads across 69 municipalities were nominated for the top spot. The most common concerns cited were potholes, poor maintenance and uneven road surfaces. “This year’s list shows that road issues are not just a Winnipeg problem or a rural problem, they’re a Manitoba problem,” Friesen said. “There is an even split between rural and urban roads on the provincial list.” Many of the roads identified are major commuter, trade and connector routes relied on by families and businesses. As governments focus on inter-provincial trade, congestion in Winnipeg and critical road safety issues, investments in the roads and highways are more important than ever. “When key routes fall into disrepair, it affects more than just convenience,” Friesen said. “Vehicle repair costs go up, fuel efficiency goes down, and delays increase. That adds pressure to already stretched household budgets and affects our economy.” Repeated nominations often signal that communities want long-term solutions, not temporary fixes. Several roads that have appeared on past lists are now under construction, resurfaced or scheduled for rehabilitation. “We’ve seen that sustained public input makes a difference,” Friesen said. “The CAA Worst Roads campaign gives governments a clear snapshot of where funding and attention are wanted most.” CAA Manitoba is urging provincial and municipal governments to continue prioritizing predictable, year-over-year investment in road maintenance and safety. “Stable funding allows governments to plan ahead, address safety concerns earlier and avoid higher costs later,” Friesen said. “It’s about keeping people safe and keeping Manitoba moving.” Top 10 worst roads in Manitoba for 2026 Provincial Trunk Highway 34 — Central Plains/Pembina Valley Provincial Road 307 — Whiteshell Kenaston Boulevard/Route 90 — Winnipeg Saskatchewan Avenue — Winnipeg Richmond Avenue — Brandon Gateway Road — Winnipeg Leila Avenue — Winnipeg 1st Street — Brandon Provincial Road 422 — Pembina Valley St. Mary’s Road — Winnipeg For more information and historical results, please visit: https://www.caamanitoba.com/advocacy/government-relations/worst-roads

CAA warns drivers of emerging auto theft tactics that prey on the goodwill of drivers featured image

CAA warns drivers of emerging auto theft tactics that prey on the goodwill of drivers

CAA South Central Ontario (CAA SCO) is warning that car theft is becoming more sophisticated and more personal, with criminals now targeting drivers directly using a mix of distraction tactics and high-tech tools. Police services across Canada have recently warned of an increase in “distraction thefts” occurring in parking lots, shopping centres, and other busy areas. At the same time, thieves are continuing to use relay attacks and key-fob signal-interception technology to unlock and steal vehicles without physical force. CAA cautions that these tactics are now being used together, creating new risks for drivers. A New Combination of Tactics This emerging method involves criminals engaging drivers in brief interactions near their vehicle while simultaneously using electronic devices to capture or amplify key fob signals. As a result, key fob-related auto theft is no longer limited to driveways or overnight incidents. Close physical proximity between drivers, their key fobs, and their vehicles can be exploited. These thefts can occur quickly and subtly, often without the driver immediately realizing anything has happened. In some cases, drivers may later notice an alert that their vehicle key is missing. This is an early sign that something is wrong. “Today vehicle thieves are becoming increasingly calculated, using distraction tactics alongside electronic tools designed to intercept or relay key fob signals,” says Elliott Silverstein, director, government relations, CAA South Central Ontario. “A brief interaction in a parking lot can quickly become an opportunity for organized criminals to target both drivers and their vehicles. Public awareness and simple preventative measures remain some of the strongest tools drivers have to protect themselves.” How Drivers Can Protect Themselves With these evolving risks, CAA is encouraging drivers to stay alert and take proactive steps to reduce their vulnerability: Park in well-lit, high-traffic areas. Be cautious of unsolicited interactions near your vehicle, including: Persistent or unusual requests for help Offers of gifts or incentives. Requests that require you to stay near your vehicle or move closer to another vehicle. Trust your instincts—if something feels suspicious, disengage and move to a safer area. Lock your vehicle immediately after exiting and confirm it is secure. Store key fobs in RFID-blocking or Faraday pouches to prevent signal interception. Keep key fobs on your person; avoid leaving them in carts, purses, or exposed areas. Consider visible anti-theft devices like steering wheel locks or two-factor authentication such as after-market engine immobilizers. Remove personal information from vehicles and clear saved home addresses in GPS systems. Report suspicious behaviour to local police. Raising Awareness Is Key CAA emphasizes that as auto theft tactics continue to evolve, awareness and vigilance are essential to reduce risk. Drivers are encouraged to remain mindful of their surroundings, particularly in public spaces, and to take simple precautions that can significantly reduce the likelihood of becoming a target of auto theft.
