Masters in a field that is related to both mathematics and computer science

<p>I am in my 4th year now ,doing a double major in mathematics and computer science , i wonder what areas would have the most intensive mathematics and require good computer science skills too. i really like both . also what unviersities in canada are good for math/cs masters ?
thanks</p>

<p>Consider CS with a specialty in theory or cryptography (assuming you like algebra and number theory type of math).</p>
