Found this spider in the Garden and do not know what it is. It is about 1.5" long and very aggressive

Nice picture and great find! This sure looks like a Foldingdoor Spider, possibly Antrodiaetus unicolor. There aren't many good pictures of this online, but it matches the description and picture found in Howell & Jenkins. They say this about this spider, "...less frequently encountered than some other species of trap-door spider." It can burrow in soft, sandy soil, on the edge of cliffs in soil and moss in rocky crevices. "The burrow often has a silken trap-door that folds in the midline...These spiders leave their burrows in the evening to hunt or repair their trap-door."

Very interesting spider, and i can see the beginning of the huge chelicerae in the picture, which helps to point toward this family. Here's another picture I found online:

Thanks for the reply. Would these be common in Canada do you know? I've never seen one before and he/she is very large. Here is a pic of the fangs
