If the weather holds out, and the school plays along it should be easily achievable in your time frame. As an example there are places in the US that offer a PPL in 2-3 weeks provided your knowledge is up to scratch. Two flights a day @ 1.5 hours and you’re looking at 15 flyable days.
You will hear people say that very few people pass in 45 hours etc. That is probably because most people don’t do it in one go - if you spread it out you’ll get skill-fade and be constantly relearning things. Doing an intensive course will be much more efficient. Any change of school will inevitably lead to more hours flown because they will have to satisfy themselves by going over what the last school taught you. The ideal scenario is: Get all the study done first, so that day 1 you can take the exams. Then all you have to do is turn up every day and fly.
The cheapest option for you is clearly a Canadian PPL. So get one. You do not need an EASA PPL to start an EASA CPL course, any ICAO PPL will suffice. You can get it validated in the UK for next to nothing so there is no need to convert anything either.
