I believe Health Canada has now allowed use of Permethin treated clothing and equipment in Canada. That will help to deter the pesky bugs.
Approved to use but you can't buy it in Canada and have to purchase abroad, anyone try mail order?

Canadian Recommendations for the Prevention and Treatment of Malaria Among International Travellers
How to Treat Clothing with Insecticides (adapted from Sawyer Products)
Before travelling, individuals should inquire about the availability of insecticide and should plan to purchase and apply these products at their destination. These products are not currently registered by the PMRA.
Select an area that is well ventilated, but out of the wind. Do not spray in an enclosed area.
Lay clothing flat on the ground, pin clothes on a clothesline, drape over porch furniture and railings, or hang clothes on separate clothes hangers, so that each garment can be easily sprayed and allowed to thoroughly dry.
One treatment with permethrin spray will remain effective for 2 weeks, including weekly launderings. An amount of 100 mL (3 fluid ounces) of permethrin spray will treat one complete set of garments (a pair of long-legged trousers and a long-sleeved shirt). Jackets, windbreakers, and rain gear may be treated in the same manner (caution: permethrin does not adhere well to some synthetic fibres).
Wear protective gloves.
Spray one side of the garment for approximately 60 seconds holding the spray can or bottle upright and 15-20 cm away from the surface. Spray in a slow sweeping motion, similar to spraying paint, to evenly coat the entire surface. Turn the garment around to the other side and repeat by spraying the second side for 60 seconds. The surface of the clothing should be wetted but not completely saturated with spray.
Hang garments up and allow the permethrin treatment to dry for 2 hours, or 4 hours if conditions are very humid.
other garments and gear (do not treat underwear):
Socks can be treated with permethrin spray. Lay socks on the ground or pin on a clothesline, and lightly spray the upper parts of socks. Allow to dry for 2 or more hours.
Polyurethane-coated nylon (synthetic) tent flaps and doors can be treated with permethrin spray. Erect tent outdoors and spray all tent flaps and doors until wetted. Leave standing for 2 or more hours to dry.
After garments have dried, pack them as you normally would for your trip. You may also want to roll up your treated clothes and store them in a plastic bag to keep them dry. Pack tents as you normally would.
(Taken from the section about bug nets)
Pour any waste insecticide down a pit latrine or into a pit dug into the ground and NOT into a river or pond, as pyrethroids are highly toxic to fish and aquatic invertebrates.

"Although permethrin is not available in Canada, travel health clinics can advise you how to purchase permethrin and pre-treated gear before or during your trip"
