There's no airline imposed surcharges on flights to/from Canada. The $141.11 amount are all government imposed taxes and fees and thus do not count towards mileage earn. However, the $330 "price per passenger" amount shown on delta.com that OP is looking at is the base fare (only the "Total Price" at the bottom includes both base fare and taxes/fees). However, the prices are in CAD. The $330 CAD will be converted to USD first and then multiplied by 5. delta.com is currently showing that $330 CAD converts to $249 USD and thus the ticket would earn 1245 miles if booked today.
