On May 13 and 15, CBSA border services officers examined two marine containers from China that were both destined for Calgary, Alberta. The containers were flagged and referred to border services officers by CBSA intelligence personnel in the Pacific Region and from the National Targeting Centre.

Within the containers, CBSA officers found 60 clear jugs and 20 blue drums containing the following precursor chemicals:

- 3,600L of 1,4 Butanediol – precursor for GHB, also known as the ‘date-rape drug’
- 500L of Propionyl Chloride – a fentanyl precursor
- 200L of Gamma butyrolactone (GBL)

The investigation is ongoing.
