Hi there..
I don't see any reason for you to loose your Canadian dream
Firstly, you have good score of 429 CRS.. though in near future, it seems that CRS cutoff will not come to these levels, but surely with many provinces coming with their own PNPs, we can expect it in early-2016. (pls done be judgemental here, this is just my opinion, no prediction or statistical observation associated with it). If there is scope for you to increase IELTS scores, You can surely go for this.
I think Quebec skilled worker stream is closed as of now.. They are coming up in with new online system of application processing similar to Express Entry October 2015.
Regarding Quebec province, one thing will go unanimously.. that French Language Skills are must for any applicant who wish to apply and to get settled in this province..
Though, there is no explicit mention about this on their website as well as they mention like it that "You can submit results of French language test, only If you wish to claim for French Language Proficiency", pls be aware of the fact that Quebec and few other provinces such as New Brunswick etc are mainly Francophone provinces and French Language Skills are required to survive/settle in these provinces.
Even, they have most of schools and education in French language only. There are very few English medium schools in Montreal, the capital of Quebec province.
Furthermore, Quebec process involves two phases.. first to get Quebec Selection Certificate and then to apply through Federal Process..
thus making it lengthier compared to EE. So, it will involve more money (for Quebec + Federal) and more time for your application to process.
However, you are the best judge of your situation and decide accordingly.
There might be other factors also to consider for this option.
Other senior members can comment about it.
Wish you Good Luck for your application !
