Your experience in oil and gas is a plus especially if you're in Alberta. However, oil companies are currently not hiring but feel free to search on the site provided above.
Your phone contact suggests you're not in Canada. This makes it tricky for you to be considered by employers. Either way, doesn't hurt to try.
