Really, your most likely path to a PPL will be through a flying school. Depending upon where in Canada you propose to learn, there will be various options open to you. The type of aircraft operated may affect your choice of school, but other than that, choosing the aircraft will not be something you have a lot of involvement in.
You will most commonly find light Cessna or Piper aircraft, with Diamond increasing in popularity on training roles. They are all fine to learn on, but each different. Ideally, you should learn on a few types, either during your flight training, or shortly after you get a PPL. There are other types, but not so common.
Alternatively, you may want to buy your own plane to learn on. This has many benefits to you, though has more up front cost.
Perhaps you may wish to refine your question, and offer a few more details about your objectives, to enable more detailed responses...
