If any guy comes to you by name of Bikram / Vikram and Amit/Amrit or from Khalsa Constructors Inc (Mind here its not Khalsa Construction) please don't rely on them. Always ask for their identity proof. They are worst work contractors in "Canada". I could have given 1 star "at least" but they are not worth of that as well.
Their quality of work is really pathetic and hardly matches with any one's standard. Even they never fulfill the requirements as mentioned in the contract. They are very eager to take payments but never finishes the work on time.
