Hi Sharon. Make 4 more good posts and you can post in the Canadian forum. There you can find out about your options for e-juice in Canada, etc. EcoVapour.com just got "the letter" from HealthCanada, so they are putting their juice on sale until June 15 (tomorrow). If you're shopping for a juice deal. After June 15, their juice will be 0mg like a lot of Canadian vendors.
Consider battery life as your first criteria for picking an e-cigarette. Many people look for something close to a real cigarette (mini) as their first kit. Then they realize that the size isn't as important as having an e-cigarette won't quit out on them several times a day. So, I would recommend a fat battery system. A fat battery also gives you the option of trying low resistance atomizers if you need more vapour and more flavour.
Also consider getting a manual battery vs. an automatic. A manual battery requires that you press a button every time you inhale, but it gives you a little more control over your vape. Also, the manual batteries are sealed so you can try dripping with them. You can try dripping new juices to see if you like them before filling up your cartridge or cartomizer with them.
So, good fat battery systems to look at would be the Ego (not the Ego-T), NoEgo, e-Power, Riva and Echo-E (manual version). They all have 510-type connectors, which is a very popular connection for accessories.
Getting your stuff shipped from outside of Canada is a bit of a problem, since Canada Customs will not allow shipments that contain nicotine juice. You should be fine shipping just the hardware, however. I've had good luck with some Chinese vendors and American sites like MadVapes.
In Canada, you can look at NicFitNation and HappyVaper for hardware. There are several other sites. Get your post count up and head on over to the Canadian Forum for suggestions.
Good luck with your decision.
