David Toneff, 33, was stopped in January by an RCMP officer in the Okanagan city who noticed a headlight was out on the vehicle.
Toneff fled and when the officer caught up to him, he discovered the car was full of guns.
"Nine firearms were located within the vehicle, four of which were loaded and one of those being a nine millimeter hand gun on the front passenger seat of the vehicle," said Const. Kris Clark..
Police also executed a search warrant on Toneff's home and found more weapons, ammunition and an American white supremacist manifesto.
"It's certainly disturbing," said Clark, "What was his intention? Where was he going? It seemed like he was going to execute something."
Toneff was charged with 25 offences and appeared in court Thursday by video.
He decided not to seek bail and will remain in the psychiatric institution in Port Coquitlan until he appears in court again in early April.
