With more than 35 years of experience, we’ve seen our fair share of lawns. But it’s how we see them that makes us the leader among Canadian lawn care service companies.

  the science behind our success

our agronomists

Lawn care threats and solutions differ based on a number of variables, like climate, region and season. That’s why our team of agronomic experts stays attuned to the conditions in your region and design services for your area based on local lawn threats and needs. They also instruct our specialists in the TruGreen TruExpert Certification Program and provide a thorough understanding of advanced lawn care techniques, products and equipment. This ensures that every TruGreen service is performed the right way, with the right equipment at the right time.

our specialists

Your lawn has specific needs that can only be met with a scientifically tailored approach. That’s why our lawn care specialists are TruGreen PhD-certified through our TruExpert Certification Program. This training is rigorous and requires annual recertification, but it ensures that our specialists develop and maintain the expertise to deliver superior lawn and landscape results. After graduation and certification, your TruGreen specialist is prepared to evaluate your lawn using our Healthy Lawn Analysis® and tailor our science-based solutions to meet your lawn’s unique needs throughout every season of the year.
