Carbapenems are considered a last resort for the treatment of multi-drug-resistant bacterial infections in humans. In this study, we investigated the occurrence of carbapenem-resistant bacteria in feedlots in Alberta, Canada. The presumptive carbapenem-resistant isolates (<i>n</i> = 116) recovered after ertapenem enrichment were subjected to antimicrobial susceptibility testing against 12 different antibiotics, including four carbapenems. Of these, 72% of the isolates (<i>n</i> = 84) showed resistance to ertapenem, while 27% of the isolates (<i>n</i> = 31) were resistant to at least one other carbapenem, with all except one isolate being resistant to at least two other drug classes. Of these 31 isolates, 90% were carbapenemase positive, while a subset of 36 ertapenem-only resistant isolates were carbapenemase negative. The positive isolates belonged to three genera; <i>Pseudomonas</i>, <i>Acinetobacter</i>, and <i>Stenotrophomonas</i>, with the majority being <i>Pseudomonas aeruginosa</i> (<i>n</i> = 20) as identified by 16S rRNA gene sequencing. Whole genome sequencing identified intrinsic carbapenem resistance genes, including <i>blaOXA-50</i> and its variants (<i>P. aeruginosa</i>), <i>blaOXA-265</i> (<i>A. haemolyticus</i>), <i>blaOXA-648</i> (<i>A. lwoffii</i>), <i>blaOXA-278</i> (<i>A. junii</i>), and <i>blaL1</i> and <i>blaL2</i> (<i>S. maltophilia</i>). The acquired carbapenem resistance gene (<i>blaPST-2</i>) was identified in <i>P. saudiphocaensis</i> and <i>P. stutzeri</i>. In a comparative genomic analysis, clinical <i>P. aeruginosa</i> clustered separately from those recovered from bovine feces. In conclusion, despite the use of selective enrichment methods, finding carbapenem-resistant bacteria within a feedlot environment was a rarity.
